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 recently,
performance and gaming issues have been spotted in 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
A mandatory security update is applied automatically and it’s
not possible for you to dodge it unless you’ve paused the
updates or modified Group Policy settings. Those with Windows
10 Home don’t have Group Policies and they can pause updates
for one month only.
As more users installed the mandatory update, gaming issues
were widely reported on forums. In fact, an Nvidia staff member

In addition to gaming issues, Windows 10 KB5001330 is also
responsible for the Blue Screen of Death errors, temporary user
problems with Windows Mixed Reality headset and enterprise

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. According to the company, “lower than
expected performance” has been observed when playing games in
full screen, borderless windowed modes and two monitors setup.
“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,”
The fact that Microsoft has acknowledged this issue is a
promising step and the company is already rolling out an update
to fix this mess.
As per Microsoft and our own testing, this fix was rolled out
via a server-side update and it does not need a full-fledged
How the server-side update works for the end user
Microsoft is deploying a server-side update that will
automatically turn off the new code that was introduced in the
latest mandatory updates. To roll back the unknown code update,
Microsoft has modified its Windows Update cloud configuration.
If your device is connected to the Windows Update service,
Microsoft will remotely disable the code changes and the device
will fall back to the previous “unmodified” code that worked
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
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.
Unfortunately, this patch is entirely cloud-based so it can’t
be verified by comparing the OS version or build numbers.
However, you can play those affected games and manually verify
If you can’t wait for the fix, you can always
uninstall Windows 10 updates manually with Command Prompt
