My system idle process is showing very high CPU usage:

Quote:
System Idle Process "In computing, The System Idle Process is a process in the Microsoft Windows operating system that displays, as a percentage, how much CPU resources are "idle" and available for use at any given time. The name of this "process" may be a misnomer, however, as the System Idle Process is more of a counter and less of a process that actually uses the resource percentage that it displays."
The OS will also issue a HLT command. That is what the CPU cooling programs like Waterfall, Rain and cpuidle (made for the Windows 9x series) was for, as 9x did not issue any HLT commands like XP/2000.

Undeletable files:

You cannot delete a file or a folder on an NTFS file system volume

First you should make sure no program is "using" the file and have it locked/in use. Close all running programs including any processes stuck from programs which has failed to closed correctly, use the Task Manager.

If the problem is frequent one possibility, other then programs messing up is the Hard Disk. So run a full disk check and get any errors fix. If it's very frequent and you are getting overall file corruption, the Hard Disk may be dying. Simple cable issues may be the problem check the cable connections and the cable itself.


Technique One: Use a tool

Unlocker
Locked Files Wizard
killbox


Technique Two: Use Safe Mode

Boot in safe mode (F8 before Win loads) and delete the file normally or using cmd.


Technique Three: Use the CMD

This can be done from both safe or normal mode. Depending on what is "locking" the file safe mode may assist, but should not be used unless needed to save the time on reboots.


1. Find the directory in which file is and copy the path and file name.

Directory: C:\Documents and Settings\%UserName%\Desktop\
File:stupidfile.exe

Or copy the full path to the file, including the Drive letter and file name extension.

Full path: C:\Documents and Settings\%UserName%\Desktop\stupidfile.exe


2. Close all open programs.


3. "Start" > "Run" type cmd press ok

This will open the Command Prompt window leave it open.


4. "Start" > "Run" type taskmgr press ok, or right click the Task bar and select Task Manager.


5. In Task Manager go to the Processes tab and find Explorer.exe then use "End Process" on Explorer.exe to kill the shell. Leave the Task Manager open.


6. Go back to the Command Prompt window and paste or type del <full path to file>. Or cd <directory path> enter DEL <filename>

Using full path:
del C:\Documents and Settings\%UserName%\Desktop\stupidfile.exe

Using directory and file name:
cd C:\Documents and Settings\%UserName%\Desktop
del stupidfile.exe


7. Go back to Task Manager, click File, New Task and enter explorer to restart the shell.

How to disable Dr. Watson for Windows

To disable Dr. Watson it's suggested (in the MS link above) that you delete the key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug. Remember to export to key first. To enable Dr. Watson again, at a command prompt type drwtsn32 -i then double-click the .reg file you exported. Note that other debuggers (such as WinDbg) will use the same key if installed as the automatic debugger.

To simply disable the auto start of debugger(s), change the "Auto" data value from 1 to 0
Quote:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug

Specifies the debugger that activates when an application error occurs. If the value of the Auto entry is 1, this debugger starts automatically. If the value of Auto is 0, the user must start the debugger. Dr. Watson (drwtsn32) is the default debugger, but another debugger (such as WinDbg or NTSD) can be installed as the automatic debugger.

Moving Windows to a new hard disk

Most hard disk manufactures have free tools for transferring the OS to a new drive, go to the manufactures web page and look for a download. For example for Seagate and Maxtor hard disks you have MaxBlast and DiscWizard, both are free versions of Acronis imaging software.

If the software provided by the manufacture is doing a drive-to-drive copy (i.e. it simply copies the files and is not using imaging) i would suggest looking at some of the free imaging software as well, because drive-to-drive copying is not always the most reliable approach. They do work but for the result to be reliable it should preferably be done "off-line", i.e. not booted into the OS.


Free Imaging Software

Intel chipset INF Update Utility:


1. Follow the steps in General.

2. Look in the key HKEY_LOCAL_MACHINE\SOFTWARE\Intel\InfInst for the installed version. Install success status, and to see if a reboot is needed at all, "reboot" on "yes/no". Start > Run > type regedit find the key.

3. Third party drivers are currently installed and/or no update is needed/possible. Which is why there is a Overwrite switch IF needed. DO NOT USE unless you know what you are doing.
Quote:
-OVER ALL: Updates ALL INF drivers even if third party drivers are currently installed. This flag works in Interactive Mode only.
4. You can also use the -B switch on the extracted setup file SETUP.EXE -b (with path) to test if a install is successful, but no boot prompt is given (Silent success), like what you should be able to see in the Registry.
Quote:
-B: Automatically reboots the system after installation. This flag is ignored if '-A' flag is specified. This flag works in either Silent Mode or Interactive Mode.

3. Disable or uninstall any emulators and/or virtual drives (blows i know).

4. If your getting CRC errors often then your RAM may be bad, run test www.memtest.org, Download (Pre-built & ISOs)


Drivers:

1. Follow the steps in General.
2. Do a manual install using the extracted file.



Manually Installing device drivers under XP:


1. Open the Device manager. Start > Control panel, click System go to the Hardware tab and click Device manager. Or Start > Run > type devmgmt.msc


2. Look for the device you want to update the driver for, double click it.


3. Go to the driver tab and click on update driver.


4. This will pop up the "Hardware update install Wizard". Select No, not this time click next. Select Install from a list or specific location (Advanced)click next. Select Don't search. I will choose the driver to install


5. Select Have Disk, click the Browse button. Navigate to where you have extracted the files/driver and find the .inf file to your device. XP will help by filtering the files by extension (inf).


Optional step:

If your in the dark about what file to use you can tell XP to search the extracted files.

Repeat steps 1 to 3:

4. This will pop up the "Hardware update install Wizard". Select No, not this time click next. Select Install from a list or specific location (Advanced) click next. Select Search for the best driver in these locations. Uncheck search removable media and check on Include this location in search. Click the Browse button and go to the directory where you extracted the files/driver, click next and let it scan, install if driver is found.

Again XP will filter the files by extension (.inf) but this time folders are excluded i.e. You can't press ok on a folder which has no driver.

Security, Virus and Spyware Help:


1. Keep your Operating System fully updated

Operating System vulnerabilities are bad and needs to be patched. Because of the level and integration at which the flaw exists they can be used to compromise systems easier and deeper. If updating with the latest service pack is giving you trouble please try making a Slipstream and do a fresh install using that new CD.


2. Keep your applications updated

Application vulnerabilities

In theory all or most applications can be misused and exploited. If the application does something it can do it wrong and that can lead to bad things if misused. Don't be fooled into thinking seemingly powerless applications are safe and pose no threat. Obviously the more popular and widely used the application is the larger the attack surface and motivation to attack will be. Looking at flaws in browsers and integrated applications like Flash, Java and Java script when used on popular sites, the numbers of people it can reach in a short span of time is quite large.

Exploits using flaws in applications can be used to attacks systems involving such things as malformed files, pdf, image, sound, video etc.

Secunia Software Inspector

These vulnerabilities start out as 0day exploits

Depending on the actual vulnerability some security programs may catch the exploit. But this will all depend on both the program and vulnerability. An example might be the windows metafile vulnerability, this was blocked by some programs generically and others needed a update. As this type of exploit always starts out as a 0day exploit most definition based protection will fail to stop the exploit at first. 0day exploits are combated using 0day protection, there is more then one type of protection which qualifies as 0day protection.


3. Secure your connection

People behind NAT routers are well protected from unsolicited traffic (guests knocking at your door you did not invite). NAT routers may have build-in firewalls and do filtering. NAT (Network Address Translation) however offers no protection for outgoing traffic, unlike most software firewalls. If you run a router remember to change the default administrator password and pick a strong pass. Disable all features of the router you don't use. If you are relying on UPnP i urge you to do the configurations manually instead, having software change router setting behind your back is not cool, if the software turns out to be untrustworthy you may have a problem (NAT Router Security Solutions). The people connecting directly to a modem should really have a firewall in place like Windows own firewall. Net-aware malware like worms do not need any user interaction to spread. Dialup'ers should take special care of spy-ware known as dialers.


4. Run Anti-malware, do system scan every week or two

Just how badly you need Anti-malware protection like Anti-virus and Anti-spyware software do somewhat depend on your habits and computer know-how. Just remember malware can come from unexpected places.

If you install software left, right and center with no regard, you surf blindly and unsafe places, well then you probably need Anti-malware protection. Or you can do what most people does who have to reinstall windows, again. Wait until you get infected and then install them for cleaning, oh and pray they can clean it so you wont have to reinstall, again. Remember protection is not used retroactively and cleaning after the fact is not how you best protect yourself, that's just damaged control.

If you have a bad habit of installing software that ends up damaging the system or if you just like to install more software then is healthy, you should look into virtual machines and virtualization in general. It will isolate and contain any issues caused by software to the guest OS, and can't harm the main system, known as the host OS. You can do a lot of testing and fun stuff without having to worry about the system (Note: Malware should be handled with care, there are procedures to testing malware in a VM).

Your browser and it's settings are also important, my recommendation is go with Firefox and use NoScript or Opera. If you use IE make sure your IE security settings are not set low and install Spywareblaster for some extra passive protection. Update to IE7 if you haven't. If you are a high risk surfer i would suggest looking into sandboxing, like Sandboxie and other forms of strong protection (Virtualization, HIPS, disaster recovery and system restore/rollback).

Understanding Spyware, Browser Hijackers, and Dialers
Malware FAQ

The scanning programs databases must be updated regularly.

It is very important to keep the Anti-virus program "database" ("signature file", "definition file") updated. The database is needed for AV programs to recognize viruses reliably. Having a updated database is needed for the programs to recognize new viruses reliably. Without a database the Anti-virus program will have to rely on Heuristics and other techniques. Even with the best Anti-virus programs that's not where you want to "lay all your eggs". Heuristics are not meant for, or to be used as a replacement for databases. When a new virus strikes, in the early stage before the database can get updated Heuristics is used.

If money is preventing you from running an updated Anti-virus program or you just feel you can't be bothered to renew your update service, i strongly advice you to pick a free Anti-virus program as the updates are what really counts. There are perfectly good free Anti-virus programs out there and compared to some old Anti-virus program with a old database, it's a "no brainer".

Data sanitization and secure deletion

Quote:
Data remanence

When most computers delete a file, they do not actually remove the contents of the file. Instead, they simply unlink the file from the file directory system, leaving the contents of the file in the disk sectors. These data will remain there until the operating system reuses those sectors to write new data.

Disk formatting

As with regular deletion, data on a disk is not fully destroyed during a high-level format. Instead, the area on the disk containing the data is merely marked as available, and retains the old data until it's overwritten by new files.
Technically what happens varies depending on both the operating system and file system used, so do the recovery method.

Gromit's Technical Guide to Partitions/Formatting/Data Recovery
Computer forensics
Peter Gutmann: Secure Deletion of Data from Magnetic and Solid-State Memory Read the Epilogue.
Can Intelligence Agencies Read Overwritten Data? A repsonse to Gutmann.

To avoid recovery of data it should be overwritten. To avoid recovery of any non-secure deleted data and data which may have leaked into free space (such as decrypted data leaked into non-encrypted free space), all free space including slack space should be overwritten. There are both free and pay File Shredding and Disk Wiping software. Some hard disk manufactures may have a utility used to do what is often referred to as a low level format (it's not really a low level format, ReInitializing). This Reinitializing will fill the hard disk with ones and zeros and should do just fine for when you are getting rid of old drives. To clean partitions/drives booting to a CD like Dban is another option.

Snake oil appears here as with most software. So if you really are in need of secure deletion and your not just doing it for psychological reasons then you should scrutinize the validity and trustworthiness of the software. Test has shown commercial secure deletion software that partially fail the secure deletion, and then there are programs that simply don't do anything. One way to do a test is to use data recovery software and see if you can recover the files you securely deleted.

Evaluating Commercial Counter-Forensic Tools (PDF)
Wilderssecurity: How to verify secure deletion
The Hard Disk Shred/Wipe Page Test shows time used for wipes with different patterns
Wikipedia: File wiping


Overwrite patterns or sanitization matrixs can be used when doing overwrite passes. The pattern is just what data is used to overwrite with. For modern hard disks a few passes with random data should do just fine. A known and pretty fast pattern is, "a character, then its complement and then random characters".

Unless you have some good reason for fearing data recovery i would not concern myself about it to much. If you have any concerns about privacy information or sensitive data purge the hard disk with random data. If you do decide to overwrite using multiple passes i would keep it down to 3 passes, say with ones and zeros and then random data. Anything more is just a waste of time if you ask me. Depending on the size of the drive it can take quite some time doing the very "secure" overwrite passes, and passes such as the 35 Gutmann wipe on a 200GB hard disk is just plain silly.

Anyway it was made for a completely different hard disk type and covers a "blend of scenarios". From the epilogue of Gutmann's paper (read the full epilogue).
Quote:
http://www.cs.auckland.ac.nz/~pgut00...ecure_del.html
Epilogue

In fact performing the full 35-pass overwrite is pointless for any drive since it targets a blend of scenarios involving all types of (normally-used) encoding technology, which covers everything back to 30+-year-old MFM methods (if you don't understand that statement, re-read the paper). If you're using a drive which uses encoding technology X, you only need to perform the passes specific to X, and you never need to perform all 35 passes. For any modern PRML/EPRML drive, a few passes of random scrubbing is the best you can do. As the paper says, "A good scrubbing with random data will do about as well as can be expected". This was true in 1996, and is still true now.

If your talking about situations with zero margin for error, then destruction is the only viable option, there are just to many variables. Software is prone to error. You will need to confirm that all overwrite passes are a success every time, so just counting the man hours or labor it's cheaper and safer to just destroy.


Contrary to popular belief data overwrite sanitization appears to no longer be approved by anybody in the US and Canada for truly sensitive information.

NSA only approves degaussing or physical destruction for hard disks.

Quote:
http://en.wikipedia.org/wiki/NISPOM

Data sanitization

DoD 5220.22-M is sometimes cited as a standard for sanitization to counter data remanence. The NISPOM actually covers the entire field of government-industrial security, of which data sanitization is a very small part (about two paragraphs in a 100 page document).[4] Furthermore, the NISPOM does not actually specify any particular method. Standards for sanitization are left up to the Cognizant Security Authority. The Defense Security Service provides a Clearing and Sanitization Matrix (C&SM) which does specify methods.[5] As of the June 2007 edition of the DSS C&SM, overwriting is no longer acceptable for sanitization of magnetic media; only degaussing or physical destruction is acceptable.

2006 NISPOM (DoD 5220.22-M)
https://www.dss.mil/portal/ShowBinar...ad_nispom.html


NIST (National Institute of Standards and Technology) only recommends overwrite sanitization for so called cleaning, i.e. to avoid software recovery methods. To protect against laboratory attacks or truly sensitive information only purging is recommend, meaning degaussing or physical destruction.

NIST Special Publication 800-88
http://csrc.nist.gov/publications/ni...00-88_rev1.pdf


RCMP (Royal Canadian Mounted Police) only allows data overwrite sanitization (i.e. cleaning) for hard drives containing the following security level of information:

Protected “A” (Protected)
Protected “B” (Protected)
Confidential (Classified)

Using triple pass, binary 0s are written on the first pass, binary 1s on the second pass and an ASCII text pattern composed of the DSX version number and date/time stamp for the third pass. Each overwrite pass is followed by a read verify pass.

For a hard drives containing the following security level of information:

Protected “C” (Protected)
Secret (Protected)
Top Secret (Classified)

Or for a hard drive which is deemed to be non-functioning. Only degaussing or physical destruction is approved.

Quote:
http://cmrr.ucsd.edu/people/Hughes/C...eProtocols.pdf
It is important to initially emphasize that erasure security can only be relative. There is no method giving absolutely secure erase. Government document DoD 522.22M is commonly quoted on erasure methods, and requires physical destruction of the storage medium (the magnetic disks) for data classified higher than Secret. However, even such physical destruction is not absolute if any remaining disk pieces are larger than a single 512-byte record block in size, about 1/125” today’s drives. Pieces of this size are found in bags of destroyed disk pieces studied at CMRR. Magnetic microscopy can image the stored recorded media bits, using the CMRR scanning magnetoresistive microscope. Physical destruction nevertheless offers the highest level of erasure because recovering any actual user data from a magnetic image requires overcoming almost a dozen independent recording technology hurdles.

I think this could be added to Task Manager issues. It was asked for a few times on this forum.

If you get a "Task Manager has been disabled by your adminstrator" error message.

1- Open Registry Editor (Regedit.exe) and navigate to:
HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies\ System

In the right-pane, double-click DisableTaskMgr and set it's data to 0

2- Get this registry fix

Boot Time:


As boot time is often asked about, i'll just post a few things.

1. Set BIOS for fastest boot

Set the HD as first boot device. Use quick boot check, default/on for most BIOS some may have a separate fast/slow check for the HD as well. Disable all devices not used on the motherboard in the BIOS.


2. Set OS for fastest boot

Disable devices and channels not in use:

Open the Device manager, Start > Run > type devmgmt.msc

Using Device manager disable any other devices not in use that you can't disable using the BIOS (not on-board etc.). With at least a decent BIOS most on-board devices like COM ports, firewire etc. can be disabled using the BIOS and when disabled they won't show up in device manager.

Using Device manager find IDE ATA/ATAPI Controller (other wording may be used, anyway it's the HD Controller) expand and double click the IDE channels > go to the Advanced settings tab and set Device Type: on None for all channels NOT in use.


Disabling Group Policy (gpedit.msc)

(*Group Policy Editor is only available in XP Pro)

Disabling Group Policy may give a faster boot. For me it seem to give a faster log off (reboot) but in any case if your not using the Group Policy i see no reason not to give it a try.

Start > Run > type gpedit.msc > right click "Local Computer Policy" and click properties > under "Disabled" check both computer and user, press apply.
Quote:
Specifies whether or not to process computer configuration settings in this Group Policy object. If you do not use computer configuration settings, select this option to start up the computer faster.

Run ProcessIdleTasks:

This will force all pending IdleTasks to complete and will invoke the boot optimization routines found in XP. ProcessIdleTasks is suggested as something to do before running benchmarks by MS, it can also be beneficial on newly installed systems to force all IdleTasks to complete.

Idle Task Scheduling: The ProcessIdleTask API

Go to Start > Run > type or paste Rundll32.exe advapi32.dll,ProcessIdleTasks hit enter, let it finish (look at the case led light), after perform a normal system defrag.

Alternatively you can also preform just the boot optimization defrag from the console: Got to Start > Run > type cmd > type defrag C: -b hit enter, when the prompt appear again it is done. Optionally BootVis can also be used and it has a on-screen visual indication of when the task has completed.


Keep the system clean

The more that has to load at time of boot the longer it will take. Learn to control windows startup of software. Don't install what you don't need. Uninstall what you don't use. Programs, windows components and features, get rid of services you do not need, remember to defrag the system drive, rebuild the registry hives (NTREGOPT)


Tools

Bootvis is a "tracing and visualization tool" which can be used to trace the boot time and load delays (drivers etc.). It can also force the file placement optimization routine to be run by using Trace > Optimize System from the menu.
Quote:
Fast Boot / Fast Resume Design

Bootvis.exe is a performance tracing and visualization tool that Microsoft designed to help PC system designers and software developers identify performance issues for boot/resume timing while developing new PC products or supporting software.

Please note that Bootvis.exe is not a tool that will improve boot/resume performance for end users. Contrary to some published reports, Bootvis.exe cannot reduce or alter a system's boot or resume performance. The boot optimization routines invoked by Bootvis.exe are built into Windows XP. These routines run automatically at pre-determined times as part of the normal operation of the operating system.

The Bootvis.exe tool is no longer available from this site.
*Note: There are some trace data issues with HT CPU's and XP SP1, hotfix exists but MS would rather you'd install SP2.
Performance trace data from the BootVis.exe tool is corrupted or missing

The file placement optimization routines invoked by Bootvis.exe is not really documented anywhere but appears to simply be the same as running the command defrag <system drive> -b from the console which im thinking is part of the ProcessIdleTasks routine. The -b switch is not documented either (i can't find it) but do "work" 1). there is a defrag performed and it's short 2.) There is no error given by the prompt.

Time wise the task performed by Bootvis fit's with the defrag <system drive> -b. The ProcessIdleTasks routine performs other tasks as well as the file placement optimization. The so called "pre-determined times" referred to is system idle time, plus the fact that the operation is done "no more often than once every three days".
Quote:
Idle Task Scheduling: The ProcessIdleTask API

The file placement optimization, which is done no more often than once every three days, is an example of a task that is carried out when the system is deemed to be idle. System Restore and other features of Windows XP also attempt to defer some work until the system is deemed to be idle. There are also some done-once-after-setup work items that also operate under the Idle Task Scheduling mechanisms.

All of these "idle tasks" are controllable by a system API in advapi32.dll, ProcessIdleTasks. The APIs sole purpose is to allow benchmarks a simple way to force any pending idle tasks to be executed immediately, without having to wait a lengthy period of time.

The API ProcessIdleTasks can be called in one of two ways, from the command line or synchronously from a program. To call ProcessIdleTasks from the command line, use this syntax:

Rundll32.exe advapi32.dll,ProcessIdleTasks

When called from the command line, the ProcessIdleTasks work is done in the background asynchronously. It can take 10 to 15 minutes for idle tasks to complete. Task Manager will report processes running, and the disk will likely be active during this time.

Rebasing dlls

Disclaimer: This is not for all and i will take NO responsibility for anything going wrong.

So what's this all about ?
Quote:
The Preferred Load Address and DLL Rebasing

All DLLs are created with an address known as the Preferred Load Address. This is the address where we want the DLL to be loaded into a process’ virtual address space. Unfortunately, many developers do not think to define a specific Preferred Load Address for a DLL that they create. Without explicitly defining one, Visual C++ assigns the default load address of 0x10000000. The result is that every time you run your application, you see messages that one or more DLLs had to be relocated. This is because they all want to load at the default Preferred Load Address of 0x10000000 and that is physically impossible.

When a DLL is loaded at runtime, the system checks to see if there is space to load the DLL at the Preferred Load Address. If the address space range from the Preferred Load Address to the load address plus the image size is not available, then the operating system loads the DLL somewhere else in memory. This means that not only must two or more DLLs not use the same Preferred Load Address, but they also must use addresses that ensure that they load outside the range required by each of the other DLLs to be loaded by the process. In Figure 4 Overlapping DLLs, A.DLL is loaded into the process’ address space first at the Preferred Load Address of 0x60000000. Then an attempt is made to load B.DLL at the Preferred Load Address of 0x60010000. However, the Preferred Load Address of B.DLL lies within the range of the address space occupied by A.DLL. B.DLL cannot overlap A.DLL in the process address space.

Rebase those dlls


With that said, here is how you rebase .dlls using rebase.exe

1. Get Rebase.exe SDK

2. Get Process Explorer to find dlls base addresses (info on dll address range later). Start Process Explorer click View > Lower Pane View > select Dlls. Then View > Select columns > go to the DLL tab and check on Base Address. Then Options > Configure highlighting > check on Relocated dlls and pick a color.

3. Use whatever method you like and works for you for editing/changing files in use, just realize that as long as the dll is in use you can't rebase it.

People who don't know how to work with system files should probably just stop now or only rebase the dlls not loaded at boot and/or program dlls easily controlled. The rest will know what the issue is and how to work around it. (*Hint* The recovery console do NOT support the rebase command).

Rebase usage: rebase -b HEX base address

Example: rebase -b 0x70000000 xpsp2res.dll



Infomation on ranges:

Quote:

A Suggested Preferred Load Address Assignment Scheme

The Microsoft documentation suggests the following scheme for defining a base address for your DLLs based on the first letter of the DLL name:

First Letter -- Base Address

A – C > 0x60000000

D – F > 0x61000000

G – I > 0x62000000

J – L > 0x63000000

M – O > 0x64000000

P – R > 0x65000000

S – U > 0x66000000

V – X > 0x67000000

Y – Z > 0x68000000

According to the MSDN library documentation, the system DLLs are currently based in memory from 0x70000000 to 0x78000000 (0x68000000 to 0x78000000 on MIPS). Therefore, you should base your DLLs from 0x60000000 to 0x68000000. It is best to base DLLs from the top of the address range down, instead of from the bottom up. Dynamic memory is allocated from the bottom up and if a DLL tries to load where dynamic memory has been allocated, it will be relocated, just as if a DLL was loaded at that address.
So what dlls to rebase ?. Well either dlls which are using bad or conflicting addresses i.e. An address which is in use and so "If a DLL cannot load at its base address because the memory is already occupied, the loader places the DLL elsewhere in virtual memory, then updates all calls into the DLL to reflect the new base address." which obviously takes time slowing the load. It can also lead to virtual memory fragmentation (see hotfix last).

I have rebased my xpsp2res.dll to the address suggested above and have seen no harmful side effects from it, however im not truly sure of the effect. But in theory xpsp2res.dll base address is bad and goes against MS's own suggested base address for system dlls (0x70000000 to 0x78000000).

There is even a hotfix for it.

Third-party programs that require lots of memory do not run in Windows XP Service Pack 2

This problem occurs if the third-party program has to reserve lots of contiguous memory. For example, the problem occurs if the third-party program has to reserve several hundred megabytes of contiguous memory. The new Xpsp2res.dll file that is added in Windows XP SP2 loads into memory at location 0x20000000. This causes the virtual memory that is available to the third-party program to be fragmented.

Information on various Tweaks:

This is just meant as a collection of information about various tweaks, both functional and non functional. Not all settings here are bad, but surprisingly many are. Either they are non functional, OS version specific, or misinformation has simply taken over and it's true function is unknown. I will add more stuff along the way.

Registry keys:

HKLM = HKEY_LOCAL_MACHINE

DisablePagingExecutive

Key: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
REG_DWORD: DisablePagingExecutive
Data: 0

Prevents pageable "User-mode and kernel-mode drivers and kernel-mode system code" from getting paged out (from memory) to disk (page file). This one is used by many and do "work" (i.e. it's not bogus). The MS documentation for workstation OS (2000/XP) mainly points to it's usefulness for debuging purposes, the server documentation also points to improved performance. However don't expect any miracles (if anything) and certainly nothing near what's often claimed by many tweak apps and guides.
Quote:
How to stop the NT Executive from paging to disk

User-mode and kernel-mode drivers and kernel-mode system code is usually written to be either pageable or non-pageable. In cases where drivers or system code is pageable, you can use the following registry entry to keep this pageable code in RAM, but this is only advisable on systems with extremely large amounts of RAM.

This entry specifies whether user-mode and kernel-mode drivers and kernel-mode system code can be paged to disk when not in use. If the value of this entry is 1, the drivers and kernel must remain in physical memory. If it is set to 0, they can be paged to disk as needed.
Quote:
DisablePagingExecutive (Windows 2000)
Specifies whether user-mode and kernel-mode drivers and kernel-mode system code can be paged to disk when not in use. Setting this value to 1 is useful when debugging drivers, because all of the code and data is always memory resident.
Quote:
DisablePagingExecutive (Windows 2003),DisablePagingExecutive (Windows 2003)

Setting this value to 1 is useful when debugging drivers, because all of the code and data is always memory resident. It also improves performance on machines with a lot of memory, because it prevents disk reads to get code or data.
Adobe referring to the use of DisablePagingExecutive


LargeSystemCache

Key: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
REG_DWORD LargeSystemCache
Data: 0 (Default value Windows XP Professional: 0 Windows Server 2003: 1)

LargeSystemCache 1 is the same setting as System > Advanced > Performance Settings > Advanced > Memory usage on System Cache.

Server OS has a Server Optimization tab in Network and Dial-up Connections which is the interface for setting the "Size" key registry data value (interface is not in XP or 2000 pro, but the "Size" key is).

"This entry (LargeSystemCache) and the "Size" entry (which is in the HKLM\SYSTEM\CurrentControlSet\Services\LanmanServe r\Parameters subkey) store the setting of the Optimization section of the Server Optimization tab in Network and Dial-up Connections."
Quote:
Because setting the value of this entry to 1 is not recommended for computers running Windows XP Professional, you cannot use Network and Dial-up Connections in Windows XP Professional to change the value of this entry.
LargeSystemCache is for file heavy I/O operation needs like the type file servers has. "It is not appropriate for application servers" (such as Web server). "Many applications, such as SQL Server and Microsoft Exchange, change the value of the LargeSystemCache entry to 0".

Win32PrioritySeparation

Key: HKLM\SYSTEM\CurrentControlSet\Control\PriorityCont rol
REG_DWORD: Win32PrioritySeparation
Data: 2

Or using the XP interface Control Panel > System > Advanced tab > Performance settings button > Advanced tab > Processor Scheduling


When you install XP this data value is set to 2 for backwards compatibility with NT (NTs version of foreground priority). XP's normal value for foreground priority is 26 in hexadecimal or 38 in decimal (the same value). If you go to Processor Scheduling and set it to Background services and apply, this will set the data value to 18 hexadecimal/24 decimal. Now set it back to Programs and apply, the value/data will change to 26 hexadecimal/38 decimal which as said is XP normal value for foreground priority. This setting as of windows 2000 has changed and now uses whats known as Quantum Accounting.
Quote:
Inside Microsoft® Windows® 2000, Third Edition Chapter 6: Processes, Threads, and Jobs (continued)
Controlling the Quantum

The registry value HKLM\SYSTEM\CurrentControlSet\Control\PriorityCont rol\Win32PrioritySeparation allows you to specify the relative length of thread quantums (short or long) and whether or not threads in the foreground process should have their quantums boosted (and if so, the amount of the boost). This value consists of 6 bits divided into the three 2-bit fields shown in Figure 6-15.

Figure 6-15 Fields of the Win32PrioritySeparation registry value

* Short vs. Long 1 specifies long, and 2 specifies short. 0 or 3 indicates that the default will be used (short for Windows 2000 Professional, long for Windows 2000 Server).

* Variable vs. Fixed 1 means to vary the quantum for the foreground process, and 2 means that quantum values don't change for foreground processes. 0 or 3 means that the default will be used (variable for Windows 2000 Professional, fixed for Windows 2000 Server).

* Foreground Quantum Boost This field, which must have a value of 0, 1, or 2 (3 is invalid and treated as 2) is an index into a three-entry quantum table used to obtain the quantum for the threads in the foreground process. The quantum for threads in background processes is taken from the first entry in this quantum table. The field's value is stored in the kernel variable PsPrioritySeparation.

The foreground process is the process that owns the thread that owns the window that's in focus. When the foreground window changes to one owned by a thread in a process higher than the Idle priority class, the Win32 subsystem changes the quantum values for all the threads in that process by using the lower-order 2 bits of the Win32PrioritySeparation registry value as an index into a three-element array named PspForegroundQuantum. This array contains values determined by the other two bit fields in the Win32PrioritySeparation registry value. Table 6-17 shows the possible settings for PspForegroundQuantum.
Quantum calculation:

Table of the three 2 bits values:


Default:

Optimize Performance for Applications:
32 + 4 + 2 = 38 Dec / 26 Hex = Short Quantum, Variable Quantum for foreground, High foreground boost.

Optimize Performance for Background Services:
16 + 8 + 0 = 24 Dec / 18 Hex = Long Quantum, Fixed Quantum, No foreground boots.

Variations:

32 + 8 + 2 = 42 Dec / 2A Hex = Short, Fixed , High foreground boost.
32 + 8 + 1 = 41 Dec / 29 Hex = Short, Fixed , Medium foreground boost.
32 + 8 + 0 = 40 Dec / 28 Hex = Short, Fixed , No foreground boost.

32 + 4 + 2 = 38 Dec / 26 Hex = Short, Variable , High foreground boost.
32 + 4 + 1 = 37 Dec / 25 Hex = Short, Variable , Medium foreground boost.
32 + 4 + 0 = 36 Dec / 24 Hex = Short, Variable , No foreground boost.

16 + 8 + 2 = 26 Dec / 1A Hex = Long, Fixed, High foreground boost.
16 + 8 + 1 = 25 Dec / 19 Hex = Long, Fixed, Medium foreground boost.
16 + 8 + 0 = 24 Dec / 18 Hex = Long, Fixed, No foreground boost.

16 + 4 + 2 = 22 Dec / 16 Hex = Long, Variable, High foreground boost.
16 + 4 + 1 = 21 Dec / 15 Hex = Long, Variable, Medium foreground boost.
16 + 4 + 0 = 20 Dec / 14 Hex = Long, Variable, No foreground boost.

Resolution of system timer

The system timer tick interval affects thread scheduling.
Quote:
Know Thy Tick

Of course the real reason why the tick interval is important is that it affects thread scheduling. The Windows scheduler gives each thread a “quantum” of time to execute before allowing another task, at the same priority level, to run. The quantum that the scheduler assigns to a thread is a multiple of the tick interval. The specific quantum value chosen for a specific thread is bit beyond where I want to go with this article.

For now, let’s just examine the default quantum value for a foreground thread in XPe. In this case the Windows scheduler assigns a quantum of 18 or 6 tick intervals (Yes, to convert quantum to tick intervals, one must divide by 3. I could throw in a gratuitous comment about obfuscation here, but the reason for the multiple is to allow the scheduler the ability to “charge” a thread for doing an operation which causes it to suspend.) This means that on my PC, a foreground thread is allowed to hog the processor for about 94 milliseconds before another task of the same priority level is given a chance.
Here is his run down on the quantum, Master Your Quantum

As mentioned, applications can change the resolution. For example running Windows Media Player will set it to 3.906 and when playing something set it to "0.977". Using the "/TIMERES=" switch in the boot.ini will set the resolution of the system timer.
Quote:
http://www.microsoft.com/technet/sys...n/bootini.mspx
/TIMERES=

• Sets the resolution of the system timer on the standard x86 multiprocessor HAL (Halmps.dll). The argument is a number interpreted in hundreds of nanoseconds, but the rate is set to the closest resolution the HAL supports that isn't larger than the one requested. The HAL supports the following resolutions: Hundreds of nanoseconds Milliseconds (ms) 9766 0.98 19532 2.00 39063 3.90 78125 7.80 The default resolution is 7.8 ms. The system timer resolution affects the resolution of waitable timers. Example: /TIMERES=21000 would set the timer to a resolution of 2.0 ms.

IoPageLockLimit

Do only work for Windows versions before 2000 SP1

http://www.microsoft.com/resources/d...ntry/29931.asp
Quote:
Quote from Inside Windows 2000, 3rd Ed.

IoPageLockLimit
Specifies the limit of the number of bytes that can be locked in a user process for I/O operations. When this value is 0, the system uses the default (512 KB). The maximum value is approximately the equivalent of physical memory minus 7 MB. This registry key isn't used in Windows 2000 Datacenter Server and is no longer used in Windows 2000 starting with Windows 2000 Service Pack 1.
Quote:
http://searchwinsystems.techtarget.c...032881,00.html
The IoPageLockLimit value was valid in NT 4.0, and in the RTM version of Windows 2000. However, as of Service Pack 1 and all subsequent versions of Windows (i.e., Windows XP, Windows 2003 Server, etc.), all references to this setting were deleted and control over the page-locking function was made totally automatic. Setting this option in anything other than the RTM version of Windows 2000 and all versions of NT 4.0 has no effect. There is no harm in putting this tweak into place, but no benefit, either.

IRQ# Priority - There are no IRQ priority boosting possibility on windows through registry entry. IRQs have a priority level at which they are interrupted by the CPU. The IRQ number (which is fix for some hardware components and otherwise relates to the install process where hardware gets detected and assigned a IRQ) determines the priority level.
Quote:
Interrupt Priority
The PC processes device interrupts according to their priority level. This is a function of which interrupt line they use to enter the interrupt controller. For this reason, the priority levels are directly tied to the interrupt number:
IRQ

Secondly if we look at linux where there's actually a app called IRQTUNE which can changes the IRQ priority of devices, it is using a kernel module, which is not quite the same as just adding a registry entry.
Quote:
IRQTUNE -- A Linux IRQ Priority Optimizer
irqtune changes the IRQ priority of devices

How do I use irqtune? Don't I have to rebuild my kernel?

No, we do not have to rebuild the kernel. irqtune uses insmod and rmmod to dynamically load and unload a kernel module. But it is correct to sense that irqtune is a kernel patch.

Unloading the DLL

The Shell automatically unloads a DLL when its usage count is zero, but only after the DLL has not been used for a period of time. This inactive period might be unacceptably long at times, especially when a Shell extension DLL is being debugged. For operating systems prior to Windows 2000, you can shorten the inactive period by adding the following information to the registry.

QoS - The actual workings of QoS, both in use, use of, technical background, OS version differences etc. is not at all well known by most, even the people using it.

1. There is no global bandwidth de/increase.
2. Only QoS aware programs can take use of the "reserved" bandwidth, 20% by default.
3. Only applies to when QoS aware programs are sending data.
4. If the program that reserved the bandwidth is not sending sufficient data to use it, the unused part of the reserved bandwidth is available for other data flows on the same host.

In my opinion people should simply uninstall the protocol, that is if not needed (VoIP stuff and the like) , removing all unneeded protocols is more likely to improve the network, this includes the file and printer sharing.
Quote:
Windows XP Quality of Service (QoS) enhancements and behavior
Correction of some incorrect claims about Windows XP QoS support

There have been claims in various published technical articles and newsgroup postings that Windows XP always reserves 20 percent of the available bandwidth for QoS. These claims are incorrect. The information in the "Clarification about QoS in end computers that are Running Windows XP" section correctly describes the behavior of Windows XP systems.

Clarification about the use of QoS in end computers that are running Windows XP

As in Windows 2000, programs can take advantage of QoS through the QoS APIs in Windows XP. One hundred percent of the network bandwidth is available to be shared by all programs unless a program specifically requests priority bandwidth. This "reserved" bandwidth is still available to other programs unless the requesting program is sending data. By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending sufficient data to use it, the unused part of the reserved bandwidth is available for other data flows on the same host.

/prefetch:# commandline "tweak"

The prefetch commandline flag is used for multipurpose programs (works generically but only WMP seems to use it). By specifying a /prefetch:# flag with a different number for each "mode" the multipurpose app can do, each mode gets its own separate hash file so as to get the prefetch done properly. It do NOT speed up the launch of programs beyond what prefetching does in the first place. Unless various dll's are used at launch time, for a "mode" of opration there is no point using it. As this is a part of prefetching and how it generically works, and all apps gets prefetch, you would think that software makers would be using the flag if it was needed for their apps, but they don't.
Quote:
http://blogs.msdn.com/ryanmy/comments/421882.aspx
WMP is a multipurpose application and may do many different things. The DLLs and code that it touches will be very different when playing a WMV than when playing a DVD, or when ripping a CD, or when listening to a Shoutcast stream, or any of the other things that WMP can do. If we only had one hash for WMP, then the prefetch would only be correct for one such use. Having incorrect prefetch data would not be a fatal error -- it'd just load pages into memory that'd never get used, and then get swapped back out to disk as soon as possible. Still, it's counterproductive. By specifying a /prefetch:# flag with a different number for each "mode" that WMP can do, each mode gets its own separate hash file, and thus we properly prefetch. (This behavior isn't specific to WMP -- it does the same for any app.)

EDIT: For stuff

DevCon quick guide

Enable/disable a device using devcon (devcon.exe copyed to system folder i.e. windows or system32 for easy access)


1. Start > Run > type cmd press ok > type devcon help for a list of all commands.


2. To disable a device first we need to get the hardware ID either by using the Device Manager or the Console and devcon.

2.1. Using Device Manager to get hardware ID;

Double click the device your interested in and go to the Details tab, using the Property dropdown menu select Hardware Ids. Depending on the device there may be multiple strings and long string with "&" connecting parts (layman term). We are only intrested in the first part of the string (ID) before any "&" character.

Example of Hardware Ids:

COM Port = ACPI\PNP0501

Sound card, first full string = PCI\VEN_1102&DEV_0004&SUBSYS_20021102&REV_04

Part of Sound card string we will use = PCI\VEN_1102

2.2. Using the Console to get hardware ID;

Type devcon /classes a list of device classes is presented. Find the device class your interested in e.g. MEDIA for sound card. Using the MEDIA device class as
example we now type devcon /listclass MEDIA, this will give a list of devices. Again we are only interested in the first part of the string before any "&" character.

Example of "devcon /listclass MEDIA".
Code:
PCI\VEN_1102&DEV_0004&SUBSYS_20021102&REV_04\4&2E98101C&0&58F0: Creative SB Audigy 2 ZS (WDM)

SW\{EEC12DB6-AD9C-4168-8658-B03DAEF417FE}\{ABD61E00-9350-47E2-A632-4438B90C6641}: Microsoft Kernel DRM Audio Descrambler

3. Continuing using the sound card as example we now have the ID and can enable or disable it by typing devcon /enable PCI\VEN_1102 or devcon /disable PCI\VEN_1102 in the console.

bat. file example.
Code:
@echo off
devcon /enable PCI\VEN_1102

Msconfig

The System Configuration Utility, aka Msconfig, is a diagnostic tool. It's used for troubleshooting and diagnosing Windows configuration issues. By using check boxes it's much easier to work with the settings, and to toggle between settings (on/off toggle style) then it would otherwise be when working with the settings in the actual files (like boot.ini), using the tools (like the services snap-in), or otherwise having to be many places, e.g. regedit, services snap-in, the boot.ini file. Check boxes also reduce the risk of typing errors.
Quote:
System Configuration Utility (Msconfig.exe) automates the routine troubleshooting steps that Microsoft Product Support Services technicians use when diagnosing Windows configuration issues. You can use this tool to modify the system configuration through a process of elimination with check boxes, reducing the risk of typing errors.
Practically non of the configurations you can modify through msconfig is meant for permanent changes, as i otherwise often see it referred to. Most of the time it's the startup programs and services which some believe should be controlled through msconfig, this is not true.

Services should be controlled using the "Services" snap-in found under your Administrative Tools. To do more advance things like deleting a service you need to use the command prompt (start > run > type cmd press ok) typing sc ? in the prompt displays all commands.

Controlling what starts up along with windows is in reality quite difficult as Windows has about a million ways to auto start programs and other stuff. This is also how and why spyware can hide it's run command from the casual PC user.

A Collection of Autostart Locations

The three places most used by legitimate programs are:

Code:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
:\Documents and Settings\*UserName*\Start Menu\Programs\Startup

I'd suggest getting Autoruns from sysinternals.

Ask the Performance Team: Who’s That Hiding in my Windows?

What to uncheck and what not

FAQ: Common Autoruns Issues


For those who are interested i'd suggest learning a bit about how windows can start stuff, as well as getting acquainted with system tools like Regedit, Services, CMD and so on.

Troubleshooting check list:


1. Look for updates to software, drivers and the operating system.


2. Run System File Checker.

Instructions: Vista / XP


3. Run a disk check. Also go to your hard disk manufacture support page and look for a diagnostic utility.

Instructions: Vista / XP


4. Test your RAM for errors.


5. Troubleshoot background running processes, use process of elimination. Autoruns is a tool used as msconfig only it's much more powerful. Process Explorer is another tool, it work like task manager only again much, much more powerful.

Part 1 : General trouble shooting
........................
Part 3 : Tweaks

I did think about doing that and it's a good idea. It's just im not sure i can have or keep each part containing only one subject, so im a bit in doubt. But i guess i can give a part a name that has all the subjects in it.

Like this "Part 3: Virus and Spyware Help, Programs, Miscellaneous stuff".

What do you think ?.
