How to Disable the Windows 10 (GWX) system tray icon in 3 simple steps (Video):

  • Jeremy Bird

    I was getting intermittent long boots and couldn’t work out why. After a lot of mucking around and outstanding input and help from Greatis S/W (Dmitry), it turned out that the boot issue started on the day that GWX mysteriously arrived on my system KB3035583 presents as Optional in Windows Updates, can’t remember about KB3031432 but I think it was in the Important list. I did a bit of research and can’t see any reason why I would want either of them. I removed them both and that process removed GWX. All good now. If you don’t know how to uninstall Windows updates, google it for your O/S. There are many ways and they’re all easy.

  • Uwe Freudenreich

    According to Microsoft KB3031432 is supposed to be a security update, that should prevent “an attacker to take advantage of the lack of impersonation-level security checks to elevate privileges during process creation”.

    See: https://support.microsoft.com/

    Does it make sense to remove this update and risk that an attacker takes over your PC??
    I’d be grateful for any advise in this, because I’m experiencing massive slowdown when booting my Win7 machine as well, since these updates were installed.
    Also the search indexer drives me crazy, since it takes more time the fuller the HD gets and I’m thinking about deactivating it.
    Many thanks in advance for a short advise.

  • Dmitrys

    Don’t touch KB3031432
    Remove only KB 3035583.
    On my opinion GWX is really useless. It slows down your computer.
    I think it’s a Microsoft way to speedup update to Windows 10.
    They used the popup warning utility on the Windows XP.
    GWX is a similar tool for Windows 7/Vista.
    You can disable GWX service and delete GX folder using administrator account.

  • Coss71

    The GWX is for when Microsoft releases Windows10. That folder is the “remote client” in your system for when the RTM version is released; when it is, the files in GWX will enable it to say bay to MS that the computer it’s on is eligible for the free Win10 upgrade and it will notify you that you can have the free update.

  • Benoit Chalifoux

    GWX=Get Windows 10, Like Coss71 said it’s for when Microsoft releases Win10

  • http://www.dirtywindows.hu/ Endless Nameless

    Illuminati confirmed.

  • Element of Light

    Remove GWX with the Windows Updater the Update names KB3035583 go to: Windows Update -> Installed Updates -> search GWX and remove it.

  • True Radiant Free

    Good info!

  • Callum

    “GWX.EXE is not a virus”. That is 100% incorrect. Programs which do similar things are regularly labelled as malware/adware/virus, therefore KB3035583 is a virus by the same definition. It just happens to have been written by Microsoft, and thats why people say that its not a virus, thats the only difference. Microsoft must really be desperate.

  • Dmitrys

    I agree with you. But Microsoft is an owner of Windows. Seems like they may do all what they want.

  • Callum

    Doesnt make it any less wrong…

  • Callum

    What is the lesson from all this? Get Linux.

  • 陳美慧

    There were few window updates notification recently and I updated the window . I used the software to remove the gwx icon. It can also remove the gwx, but the gwx re-install and appear automatically after 2 days. Please update the software in order to remove the gwx permanently, thank you.

  • Dmitrys

    Thanks!
    I have updated GWX Stopper 1.2.
    Please, try it.

  • Ken

    Well I’d agree with one of your statements… the way Microsoft placed this aggressive program into the KB3035583 “important update”, is a new low for MS. As the full and “complete” removal requires uninstalling and blocking this update, along with editing ones registry to remove any remnants,…or that dam aggressive GWX.exe will find it’s way back. (Many are reporting this on the net)

    So GWX.exe is definitely resembling the actions of a hidden virus or aggressive spyware, and even could be considered a type of Trojan for MS to enable when the roll out of Windows 10. Not informing customers that a sneaky aggressive program will be included or installed on ones toolbar advertising an ad for a future product, or even providing the option of “easily” uninstalling this unwanted program is just wrong.

  • Joe Citizen

    No, Microsoft owns the copy right to Windows but they do NOT own windows. That is the same as saying the grocer owns the food you bought from them or the car manufacture owns the car you drive. If you paid for it, YOU own it…

    And as the owner you may tweak it, tear it down and decompile it or whatdafuckever you want to do with that copy as it is yours and Microsoft is no longer the owner of that copy of Windows or whatever juckware they sold you…

  • Shadow Wolpertinger

    It’s NOT required for windows 10 because windows 10 is free. You don’t need a system slowing program or a coupon or a recommendation of any kind ect. When win-x comes out it will be free.

    Now if only they’d give ALL versions of windows downgrade options.
    Instead of just select versions like Professional. I hate windows 8.1
    but don’t want to pay for a new OS. Since it’s not pro though I don’t
    get the free downgrade options.

  • marklar

    Nice program, thanks

  • Peter

    GWX.exe is an ADWARE!
    It started to disturb me with popups to “notify me” about the “free” Windows 10 upgrade.

    Once when it shows up first time, I chosen that I didn’t want to upgrade to Windows 10, because this computer is my company’s computer, so the upgrade is not so easy.
    Until today it does not disturb me.

    Today it started to show popups, that “My Free upgrade is waiting…”
    I could not close this popup.
    When I close the disturbing popup, in few seconds later it shows up again-and-again.

    Thus I mark this program as an adware and I’m going to remove it from the computer.

  • Callum

    It is adware. There is no nice way of saying.

  • eSage

    Apparently someone hasn’t read their EULA. You do NOT own Windows. You did not BUY Windows. What you paid for was the right to USE Windows. That operating system on your computer is still owned by Microsoft.

  • IT-user

    GWX.exe is a Malware and Adware software, developed by the corporate people at Microsoft. There is no other way of saying it. This is the truth.

    no
    MS is the vendor of my win7
    that’s why I have that ridiculous Product Key
    I am the owner of the system
    and search updates before I install them
    win 10 installs updates automatically

  • Dmitrys

    I have updated GWX to version 3.0.
    Now it block GWX.EXE and other related processes from running.
    If a Windows update reactivates GWX you will see a GWX Stopper window, but GWX will never run.
