Last week we reported on a problem with recent Windows 10 KB updates that were causing issues for gamers. Nvidia was recommending gamers to roll back to an older version of Windows. However, that would leave the platform vulnerable to bugs that the KB updates patched. Microsoft is now rolling out a patch to fix the problem.

More specifically, the company is sending out a Known Issue Rollback (KIR), which solves the gaming issues. With this KIR, Windows 10 users can rollback to a previous state, removing the gaming problems without losing the security fixes.

This is also the first time the company has acknowledged the issue:

“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”.

Two KB updates are causing problems for games, KB5001330 for Windows 10 20H1 and KB5001337 FOR Windows 10 1903 and 1909. The patch was creating issues for gamers, who are seeing shaky framerates, stuttering performance, and other game-related bugs.


Microsoft stayed quiet while gamers complained about the bugs, but Nvidia advised users to uninstall the affected KB releases. It is also worth noting it’s not NVIDIA machines that are facing problems. Users of AMD-powered gaming PCs are also in the same situation.

Nvidia’s advice didn’t really solve the problem because while it allowed gamers to avoid the bug, it meant they were missing out on important patches. In other words, Microsoft needed to step up.

This week, the company is finally reacting to the issues with the release of the KIR. This is a type of update that allows Microsoft to target specific on-off updates:

“This issue is resolved using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices. Restarting your device might help the resolution apply to your device faster. For enterprise-managed devices that have installed an affected update and encountered this issue, it can be resolved by installing and configuring a special Group Policy.”

Tip of the day:

If your PC keeps connecting to the wrong WiFi network, you can set WiFi priority to avoid the need to manually select access points over and over again.
