Microsoft appears to be blocking even more apps for customizing the user interface in Windows 11 24H2. Users noticed that ExplorerPatcher joined the recently blocked StartAllBack app.
TLDR: StartAllBack, ExplorerPatcher and some other projects are being blocked on 24H2.
A Microsoft representative (?) opened an issue for Explorer Patcher:
Hi Team,
This is to let you know that Win10 taskbar code is removed. And if use continue to use ExplorePatcheron Windows GE Build, they will see a crash. You only need to adjust the setup exe name to get around the block in your new version. We will continue to block ANY version that crashes Explorer.
