Microsoft fixes bug that made Task Manager partially unreadable

Microsoft has addressed a known issue that made parts of the Task Manager unreadable after installing the KB5020044 November preview update on Windows 11 22H2 systems.

As Redmond explained when confirming the issue two weeks ago, affected users see some user interface elements of the Task Manager displayed using unexpected colors that make them unreadable.

The bug behind these UI problems was fixed in the Windows 11 KB5021255 cumulative update during this month’s Patch Tuesday.

“This update addresses a known issue that might affect Task Manager. It might display certain elements in the user interface (UI) in unexpected colors. Some parts of the UI might not be readable,” Microsoft explained

“This issue might occur if you have “Choose your mode” set to “Custom” in the Personalization > Colors section of Settings.”

The Task Manager display bug should not impact Windows 11 users who picked Dark or Light mode in the Settings app.

Workaround also available for affected users

Microsoft also provided a temporary solution that should help affected Windows 11 22H2 customers who haven’t yet installed the December 2022 Patch Tuesday updates mitigate the issue.

The workaround requires impacted users to choose either Dark or Light for the “Choose your mode” setting.

To do that, they need to right-click on the desktop, go to Personalize > Colors, and then select “Dark” or “Light” for “Choose your mode.”

This month’s Patch Tuesday updates also addressed an LSASS memory leak issue that led to freezes and restarts on some domain controllers after deploying last month’s Windows Server updates.

Unfortunately, Microsoft confirmed that Windows Server updates released during December’s Patch Tuesday would trigger errors when creating new virtual machines on some Hyper-V hosts. 

However, only Windows Server 2019 and Windows Server 2022 should be impacted after installing the KB5021237 and KB5021249 Patch Tuesday updates.
