Windows 10 appears to be getting a new server-side update and it’s one that you might want to apply if you’ve been having any kind of performance issues, such as stuttering, flickering or text rendering issues when playing certain games.

As we reported, performance and gaming issues have been spotted in at least two Windows 10 updates – KB5001330 (mandatory security patch ) and KB5000842 (optional update).

Back in March, Microsoft published KB5000842, which was an optional update aimed at fixing performance and printing issues caused by March’s Patch Tuesday update. As expected, this update ended up introducing even more problems for some users, including gaming issues.

Microsoft appears to have been made aware of performance issues last month. However, it seems to a slipped into Windows 10 KB5001330, which was recently released as a mandatory security update.

As you may be aware, a mandatory security update is applied automatically and it cannot be skipped unless you manually pause updates or use group policies. As a result, gaming issues were widely reported over the past few weeks, and several users uninstalled the update.

KB5001330 gaming issues confirmed

In an update to the support document, Microsoft has finally confirmed that an issue in Windows 10 updates is affecting a small subset of users.

“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,” Microsoft noted.

To address the gaming issues, Microsoft appears to have made a change in the cloud configuration, and devices connected to Windows Update (WSUS) are automatically notified of the change.

Once this happens, Windows Update will automatically turn off the new code that has a problem, but users won’t be notified when this happens.

The fix is still rolling out and it might take up to 24 hours to propagate. Some affected users told us that their games are running smoothly after they checked for updates and restarted the system manually.

If you want to apply the patch immediately, check for updates and restart your device.

Remember that the patch won’t show up in the Windows Update Settings.
