Windows timer resolution tool in form of system service

For info on topic just search for NtSetTimerResolution.

First version (C++ implementation) of system service:

First version (C# implementation) of system service:
http://www.mediafire.com/download.php?i36a8qbi5usa3b6

Second version (C# implementation) of system service (capability of specifying processes for a timer resolution added):
http://www.mediafire.com/download.php?by934opu8qox9wc

All packages contain `Readme.txt' and exe-file.
Packages of C# implementations also contain cs-file - C# source file which can be compiled to exe-file with C# compiler 'csc.exe' (located in .Net framework folders).

Second version was implemented for gurus who would notice any process demonstrated weird behavior with maximum timer resolution.

Differences between versions 1 and 2:
First version of service just sets maximum timer resolution upon its start.
Second version of service looks for 'SetTimerResolutionService.exe.ini' file with processes list, and with non-empty ini-file presence following logic is implemented:
- run process start monitoring;
- set maximum timer resolution upon first instance of any of listed processes start;
- set default timer resolution upon last instance of any of listed processes stop.
In absence of ini-file second version does the same logic as first version.
In presence of empty ini-file second version does nothing at all.



Universal PowerShell script for set timer resolution service installation:
http://www.mediafire.com/download.php?xl0c0r12470rff0

If you have nether executed any PowerShell scripts, then running

Code:

Set-ExecutionPolicy unrestricted

in PowerShell as the fisrt step is mandatory, because PowerShell restricts script execution by default.

Just place sript into folder with service`s exe-file. Start script either through context menu or in PowerShell.
Script is capable to install (and re-install) all mentioned above versions of service.
Script installs service with acount 'LocalSystem'.

Spoiler

Script`s actions are:
- Check folder-owner for an exe-file of service.
- If exe-file is absent then check folder-owner for a cs-file of service (source file) and invoke C# compiler to build exe-file.
- Check for a previous instance of STR service.
- If STR service already installed then stop and uninstall it.
- Install new instance of STR service and run it.
Script creates log-file.

Dear gurus, you can tweak source file of service yourself and rebuild exe-file of service with help of this script - just rename old exe-file.

There is also Cyberdyne`s script-installer

Cyberdyne also did full package with all vesrions and install script (bat-file):

Update for Win11:
https://github.com/amitxv/PC-Tuning...on-in-windows-after-the-the-great-rule-change

Code:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel]
"GlobalTimerResolutionRequests"=dword:00000001

I think I may have messed up something.
What services does this rely on to start? Because now when I start it is says

"The Set Timer Resolution Service on this local computer started and then stopped. Some services start automatically if they are not in use by other programs"

I figure I must have turned something off that it needed but I'm not sure where to start...

Already tried reinstalling it.

 

Give me details, more info, ...
- Which one version do you use?
- Did service worked and then you performed any actions and it stopped work? Or it suddenly stopped work?
- What OS do you have?

There are no dependencies in this service. It only depends on .Net framework (or on C++ framework). (And I didn`t touch service`s source files for a many days).
If service started mailfunctioning after you executed new installation script, then possible cullprit is account 'LocalService'. Is there log-file 'STR_Install.log'? And what events do you see in Event viewer?

You can troubleshoot by installing service manually with account LocalSystem:
sc.exe delete STR
sc.exe create STR obj= "NT Authority\LocalSystem" binpath= "c:\...\SetTimerResolutionService.exe" displayname= "Set Timer Resolution Service" start= auto
(or with InstallUtil.exe)

In PowerShell you can look at events related to service:
Get-EventLog -Source STR -LogName Application
Get-EventLog -Source STR -LogName System


Another thought - second version of service in presence of non-empty ini-file depends on state of WMI subsystem.

Edit: I was wrong about default account - it is namely "NT Authority\LocalSystem" (not "NT Authority\LocalService").

 

I was using the second version with no INI file. It was working fine, I messed with some services and clean up some reg crap, and on restart it started acting like that. I think it may be related to Von Dach's tweaks, but I opted for his tweaks that left WMI alone (because I know your service would probably need that untouched). And I use Windows 7 x64.
Your log files only tell me that the service was correctly installed.

I'll give the first version a try...

Edit: The first version using C# did not work, but your C++ version seems to start...

 

That`s strange because both first version implementations do nothing except for NtSetTimerResolution call... Only difference between them is .Net platform.
Did you look in event viewer? To simplify events searching you can clear event logs ('Application' & 'System') before service start attempt.
(In PowerShell:
clear-eventlog -log application, system
start-service STR
(get-service STR).WaitForStatus('Running', [System.TimeSpan]::FromSeconds(10))
get-eventlog application >> some_file.txt
get-eventlog system >> some_file.txt
)

Edit: BTW, I implemented two utilities for Von Dach`s performance package:

Both can be used for a backup purpose.

 

Gj.

This is 4 more letters.

 

I used his L3 services set up. Which turns off event log/viewer it seems... lol
Could that cause this problem in the first place?
Also, is it important to point out that version 1 and 2 of C# run in x64, but the C++ version runs in x86? (identified by the *32 addendum in taskmanager).

 

Well... As service writes to the event log, those writes can cause an exceptions... I will check this moment and be back...

Edit: I inserted checks and interceptions into lines with event logging in both C# versions. You can redownload them packages from links in first post. And if my corrections do the job, then you can re-pack and re-upload your cumulative package.

 

Alright, thanks. Giving it a try now, will edit this in a bit...

Yup, all fixed. Starts fine now.
Here is the adjusted pack

Thanks to you - that was a perfect suggestion about disabled event logs... Link in OP I replaced.

 

Btw, I vote this for sticky.

 

Update for PowerShell script 'Install-STRService.ps1' - read OP...

 

Some thoughts about timer resolution and CPU power settings
http://forums.guru3d.com/showpost.php?p=4564488&postcount=517


Here is PowerShell script for unhiding most interesting (but not all) CPU power settings:
http://www.mediafire.com/download.php?m3cgvw73c03fn47

After script execution go to the 'Control Panel > Power Options > Change Plan Settings > Change Advanced Power Settings' and in dialog window you locate 'Processor power settings' tree root node - there live all unhidden settings.

 

Not sure if should post in response here or the thread on the other section since you post everything in both places anyway lol.
But I understand, traffic and all.
Thanks for the convenience.


Uh. Not sure why. But, rightclicking the file and selecting "Run with Powershell" makes a prompt show up, but then some red text shows up and it closes too fast for me to read it.

I remember you saying how you need to make your ps1 scripts with work with a newer version of something another because Windows 7 is different by default?
IDK. I just know it aint working.

 

Just run PowerShell and execute script there. You will see error text... Send it to me:
$error[0] > c:\somefolder\errors.txt
- saving error text to file after script execution.

May be you already deleted 'Attributes' values under those regystry keys (or one key). Do you see mutliple settings in mentiond dialog under CPU settings tree node?

 

Well, I added the cpu parking options a long time ago.
Anyway, this is what I get.

 

Execute inside PowerShell

Set-ExecutionPolicy RemoteSigned
or
Set-ExecutionPolicy Unrestricted

PowerShell by default restricts script execution. So user must set this policy to allow script execution.
For a help:
get-help Set-ExecutionPolicy -online

 

Ok, that worked wonderfully (setting it to Unrestricted that is). Sorry, never touched powershell before.

So many options. So many.

 

I am using PowerShell for 2 years now and I keep finding new things and aspects and tricks. I`m in love with this shell! It was created for IT professionals but thing is it can be used at any level of difficulty.

Here is entry points into PowerShell world:

1. get list of commands:
- all
get-command > c:\somefolder\all_commands.txt

- started with 'get' verb
get-command "get-*"
or
get-command -verb "get"

- having 'process' in noun part of command name
get-command "*-*Process*"
or
get-command -noun "*Process*"

2. get help on any command:
get-help get-command -full
or
get-help get-command -online

3. command or path completion with Tab - start typing a command or a file path and then press Tab to let PowerShell to complete it for you (and press Tab until you get needed command)

4. look for all properties and methods of items returned by a command (PS not always shows all properties and it doesn`t show methods):
- all properties
get-process -name notepad | format-list *

- all public members
get-process -name notepad | get-member

- Tab completion of property or method of item
$notepad = get-process -name notepad
$notepad. - and press Tab so PowerShell shows you all avaliable properties and methods one per Tab press

5. if you don`t want to look at screen output you just redirect output:
- to file
get-process | out-file c:\somepath\all_processes.txt (recreates file)
get-process | out-file c:\somepath\all_processes.txt -Append (appends to file)
get-process | add-content c:\somepath\all_processes.txt (appends to file)
get-process > c:\somepath\all_processes.txt (recreates file)
get-process >> c:\somepath\all_processes.txt (appends to file)
(if path contains spaces then take it into quotes)

- to a special window with table view
get-process | out-gridview

- to allow PS-scripts execution
Set-ExecutionPolicy RemoteSigned
or
Set-ExecutionPolicy Unrestricted
