Vole has warned that the Task Manager might become unreadable for some customers after installing this month's KB5020044 preview update for Windows 11 22H2 systems.

Microsoft said that after installing KB5020044, Task Manager might display certain elements in the user interface (UI) in unexpected colours. On affected devices, Task Manager should function, but some parts of the UI might not be readable.

Users affected appear to have set  "Choose your mode"  to "Custom", in the Personalisation -> colours section of Settings."

Users who have picked Dark or Light mode in the Settings app shouldn't be impacted by this Task Manager display bug, according to Vole.

Microsoft is working on a fix to address this known issue and says it will provide an update in an upcoming release.
