Windows 11 22H2: December 2022 update (12/13/2022) fixes Task Manager display issues

Windows[German]The preview update from November 29, 2022, had caused a display issue in the task manager of Windows 11 22H2. Its display could hardly be read in certain display constellations – a German user notified me in a comment within the German blog. The security updates from December 13, 2022, fixed this problem, as Microsoft and also the user confirmed.


The task manager display issue

I had reported in the blog post Windows 11 22H2: Preview Update KB5020044 (Nov. 29, 2022) about the preview update KB5020044 from November 29, 2022. Microsoft released this update  at the last minute and corrected numerous bugs. Shortly after the blog post was published, German blog reader McAlex777 reported within this German comment a display bug in the Task Manager:

Installed today, and the following error:

When "Color scheme default is dark" and "Color scheme app mode is light" (i.e. taskbar dark, apps light), task manager appears in "dark" mode, with dark font and cannot be made light either (see above image). Other apps are normally bright.

If the "color scheme" is completely dark or completely light, the task manager behaves correctly.

This bug was then confirmed by Microsoft on November 30, 2022 on the Windows Release Health Status page of Windows 11 22H2 in the post Task Manager might not display in expected colors. I had addressed the issue in the blog post Windows 11 22H2: Microsoft confirms display bug inTask Manager caused by update KB5020044.

December 2022 update fixes the issue

Blog reader McAlex777 then got in touch with a comment on December 14, 2022, and wrote that the one in Task Manager was fixed. However, he personally complains that the following issues still bother him:

  • No full text search
  • The performance view with the single graphs per CPU/GPU core is confusing
  • You should be able to hide devices in the performance view

In the meantime, Microsoft has also confirmed on December 13, 2022 that the display problem with the Task Manager in Windows 11 22H2 has been fixed. On the Windows 11 22H2 Health Status page, you can find the article Task Manager might not display in expected colors which reveals the details.


After installing KB5020044, Task Manager may display certain user interface (UI) elements in unexpected colors. On affected devices, Task Manager should work as expected, but some parts of the UI may not be readable.

By changing the color scheme, this display issue could be mitigated – but with the update KB50212555, the problem is finally fixed.
