Microsoft fixed the Windows 10 game performance issue

Some Windows users reported game performance issues after installation of the Windows 10 updates KB5000842 and KB5001330. The updates were released in March and April of 2021 to devices running Windows 10 version 2004, 20H2 and 21H1.

Ashwin wrote about the game performance issues caused by KB5001330, stating that users reported game performance drops after installation of recent Windows 10 updates.

Microsoft confirmed the problems later on. The known issues section of the updates in question contain the following description:

A small subset of users have reported lower than expected performance in games after installing this update. Most users affected by this issue are running games full screen or borderless windowed modes and using two or more monitors.

Games can be run in the three game modes full screen, borderless window or windowed.

Microsoft has a fix for the issue which will be deployed automatically to "consumer devices and non-managed business devices". The company is using a new feature, called Known Issue Rollback (KIR) to fix the issue on affected devices. The feature enables Microsoft to "quickly revert a single, targeted fix to a previously released behavior if a critical regression is discovered".

KIR is supported in all Windows 10 versions starting with Windows 10 version 2004; some earlier versions have partial support for the feature only.

Microsoft notes that it may take up to 24 hours for "the resolution to propagate automatically". A restart of the device may apply the fix faster according to Microsoft.

Enterprise-managed devices need to install and configure a "special Group Policy" according to Microsoft. Administrators may download the MSI file on the support pages, e.g. this one. The link is listed in the workaround column of the described issue.

Closing words

Windows gamers who are affected by the game performance issue should see performance restored over the course of the next 24 hour period.

    Hey guys quick question do i have to do something to fix the issue or just wait?

    1. Martin Brinkmann said on April 25, 2021 at 8:31 pm

      Just wait, it is applied automatically.

        well seems like im facing still the same issues even after applying new microsoft updates..

    I just installed Windows 10 Pro and I feel like I already lost control of it.

    – twice KB4023057 but without unistall option
    – KB4601554 Cumulative Update Preview for .NET Framework (after ‘hard pro user’ update settings still start if I check for update). Isn’t a preview?!?
    – dayly Privatezilla telemetry reset (regarding dmwappushservice reset to manual). It seems related to KB4598291 (but my ISO is from march)

    PS (funny): now I have to scroll System Explorer to see all active processes… … What a mess!

    My laptop was working fine before the update. Even after a rep suggested I go to best but to download a clean version of the update, I still can’t use my computer. I ghosted my laptop for now reason. Windows still won’t download properly. 😕

      Same thing happened to my one year old HP laptop which I use only for MS Office. I don’t even have any games on it. I had to use my installation usb to trouble-shoot/repair, but the only feature that worked to resolve the problem was a re-install of Win 10. I HAVE NOT accepted update KB5001330 this time around and laptop functions normally again.

    Do you really think that Win7 has NO Telemetry?

    KB3075249: Update that adds telemetry points to consent.exe in Windows 8.1 and Windows 7
    KB3080149: Update for customer experience and diagnostic telemetry

      @ BogonIP

      I have news for you. Win 7 users (so called tin foil hat wearers) blocked auto updates until the experts such as Martin Brinkmann explained what the Win 7 updates did. Consequently, most Tin Foilers did not install the KBs you mention nor did they install other dubious KBs.
      It soon became obvious that Win 10 was a NOT a Desktop/Laptop OS but a UWP (Universal Windows Platform) that was NOT fit for purpose and full of bloat and bugs

      So, as Anonymous said, enjoy being MS Win 10 guinea pigs. :)

      NB. FYI, I installed Win 10 on my Laptop 3 years ago. Before I did I cloned my Win 7 hdd then installed Win 10. It was useless ! It screwed a lot of programs, drivers, etc, etc.
      I removed the borked hdd and formatted it. I installed the clone drive. Since then I have had no

      I repeat enjoy being MS Win 10 guinea pigs. :)

        Would rather use an up-to-date OS any day compared to a 12 year old dinosaur with no support for latest tech. Win10 works fine, although from your comment it’s clear why a non-tech person like you might have had issues you simply didn’t know how to fix.

        @ Jack

        “a non-tech person like you”

        Such assumptions from an obvious troll.

        My employment in Computers

        6 years with Hewlett Packard as a field service engineer repairing HP 3000 mini computers and peripherals.
        8 years installing DEC PDP11 mini computers and peripherals.
        7 years with Novell as Technical Support Manager supporting Distributors technicians and installers in Europe, Middle East and Africa (EMEA)

        “Win10 works fine”. Did you read ths article and its subject ? No, thought not.

        You must work harder if you want to be a successful troll.

        @Tom Mc

        I find it very Ironic and Stupid.

        That Tom Mc is more worried about Win 10 Telemetry that posting half his IT Resume on this website, just to make his point.

        You would think a person that has 7 years of Technical Support Manager, would understand NOT to post his/her Personal/Private Information on this website. Seems like to me you’re more worried about Win 10 Telemetry than your Own Private Information on the Internet.

        I’m glad to see you’re not letting your education get in the way of your ignorance Tom Mc.

        Nothing wrong with using an older operating system if you don’t receive any benefits from an upgrade. There’s definite pros and cons depending on the individual scenario. For example I support a VDI environment for a few thousand overseas employees and Windows 10 is the only version desktop OS with a multi-session image in the Azure Gallery for WVD deployments. (Used Citrix XenServer before and I would never go back.)

        That and the ability to use autopilot with Intune for zero-touch new user setups (Win7 is marked a downstream device for hybrid joins and doesn’t work with dsregcmd). I can send out a bare metal laptop and have the user on the VPN within an hour of receiving it.

        But for the average home user really nothing has been added since Win7 that drastically improves a day-to-day experience. Saying that though this holier than thou attitude as if you’re special for simply not changing really paints the rest of us in IT in a bad light. Educate users, don’t mock them.

    Laughs in Windows 7. Enjoy being Microsoft’s guinea pig on Windows 10.

      Uses another unsupported OS from same company and consists himself superior. lulz Watta moron!

    Why are all update issues said to affect “a small subset of users?” This one supposedly affected those with “better” graphics cards and NVidia, for one, said to uninstall the updates.

    Now MS is doing dark of night fixes to fix the fix gamers already fixed.

    Nice MS decided to do something but not much though seemed to go into who the “small subset of users” mostly are, gamers good enough at gaming that they almost certainly do manual updates and will have this fix blocked because the bad updates have already been removed. The original issue will get fixed properly in a few weeks by a future update.

    Enterprises are advised to do the KIR change which appears to just remove the bad updates also but probably won’t unless there are complaints. Do they get the dark of night double or triple fix, too?

    You know what game I like the best? Microsoft’s Telemetry.

      Ha ha, you so funny! /s

      Also brave, giving up your day job to be a failed comedian…

  9. richard allen fraser said on April 24, 2021 at 7:49 pm

    How will we know its been fixed? Can I just go into update history to see the fix?

    1. Anon said on April 26, 2021 at 1:14 am

      Didn’t you experience any issues with the update? So isn’t it obvious how you would know? Jeez…
