Windows 11 22H2: Preview Update KB5031455 (October 26, 2023)

[German]Microsoft has released the optional cumulative (preview) update KB5031455for Windows 11 version 22H2 on October 26, 2023. This brings a number of fixes (similar to the preview update for Windows 11 21H2). Below I give an overview regarding these (Moments 4) updates for Windows 11. According to user reports, the update seems to correct the problem of the shadow font that cannot be switched off.

It should be noted that this update is a so-called preview update. This is optional and must be manually triggered for download and installation by default (although Windows 11 22H2 includes options for automatic installation). The update contains the fixes that will be rolled out in the security update for the following month. The list of updates for Windows 11 can be viewed on this Microsoft page.
