Windows 10 KB5001330 gets fix for performance issues

Last week, we wrote about issues with the Windows 10 KB5001330 update. Since the installation of this patch, a bunch of users are experiencing a variety of problems, including game performance issues, crashes, error messages, screen flickering, network issues, etc.

Now we hear there's an emergency fix for the KB5001330 update. Windows Latest writes Microsoft pushed out a server-side update for Windows 10 that resolves some issues problems. Microsoft has admitted that KB5001330 caused lower gaming performance for "a small subset of users."

Emergency cloud-based update for gaming issues

The emergency fix is not a full system update and is installed in a more sneaky way. When Windows connects to the Windows Update service, Microsoft will remotely disable the troublesome code changes to make your computer fall back to the pre-patch conditions that didn't cause performance problems.

The server-side update is gradually rolling out this weekend and you won’t see anything when you check for updates. Some affected users told us that their games are running smoothly after they checked for updates and restarted the system manually.

If you think the fix is not available for you, try launching the Settings app and manually check for updates. You don’t have to apply any updates from the Windows Updates. Once you’ve checked for updates and your device has communicated with the Windows Update server, you’ll need to restart the device.

The patch is rolled out gradually. To see if your computer has the update you need to open the Registry Editor and navigate to the following key:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFeatureManagementOverrides41837593227

If you’re able to access the above location and you can see the “EnabledState” entry with value 1, that means the fix has been applied.
