    The “slow” way to disable IPV6
    For years, KB 929852 has documented manual and fix-it methods to disable IPv6 by setting DisabledComponents = 0xFFFFFFFF under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\.

    [​IMG]

    It was recently discovered that disabling IPv6 with the above registry value causes a 5 second boot delay in the Pre-Session Init Phase of OS startup.

    IS that the same outcome as unchecking "Internet Protocal VersionV6 (TCP/IPv6) in Local area Connection properties?

    I never bothered disabling any of those, I leave it default.

    I guess not, because unchecking IPv6 at connection properties you disable IPv6 for that connection, not globally.

    Ok, cool.
    Since I use Windows Mail I will have to remember to not disable IPv6.

    Why would I disable IPv6 to begin with? :-/

    For a long time, I see sites recommend disabling components that are not used. I never did this but this "tweak" is supposed to help.

    You don't see it so much lately (Win10) but older W95, XP etc.
    here some info, go down 3/4 of page
    https://www.tweakhound.com/2015/12/09/tweaking-windows-10/15/

    If you Google "Disabling IPv6" you will get a whole bunch of links for doing it or not doing it.

    Looks like it's the same group of people who believe that entering "-fastasfuck" in your CS:GO launch commands will lower your ping by 90% and make the game run at 5000 FPS :p

    In other words, "I've read some stuff on the internet by random people and without any justification given, thus it has to be true."

    I use to disable it cause at one point it was causing lag in games, online but that back when first came out?

    I think since then I just keep disabling it from Ethernet properties, I think this install of windows 1803 it first install of windows in over decade I left it on.

    I dunno. My Windows 7 install has gotten to the point where every so often it hangs for 30 seconds on boot before the login screen. May as well try it out. I have another install ready, but I think I'm taking my win 7 machine offline except for occasional updates. Fudge spectre patches, fudge windows updates. Hello Linux internet browsing.

    I think at this point you may as well keep all your work stuff on a separate machine and have a dedicated net browsing machine. The idea of a secure machine connected to the internet sounds a bit oxymoronic now. At the very least, only connect to the net when needed. Having an always on connection kind of seems dumb at this point. Like how cars didn't have seat belts for a long time and now it seems like the dumbest thing ever.

    Btw, it was confirmed by several gurus in 1809 thread that some UWP apps do not work without IPv6.

    For clarity and in defense of tweakhound, that page says to NOT disable IP6. Unlike most of the internet including this forum with their "-fastasfack" switch, he's generally evidence-based and logically sound with his tweaks, so ....there it is.

    Yes, I posted that link as he gave some examples to why enable and disable (he recommended to leave it enabled).

    don't disable ipv6 period.

    parts of the OS actually require it enabled these days.

    I disable it, together with the IP6to4 Helper .. I like living on the edge, you know? :D

    Better: "Don't disable IPv6 if you don't know what you're doing!"
