Windows 11 - File Explorer Bug

So I managed to find the root cause of this issue.

I randomly looked at the Windows Explorer on my personal computer and noticed, that it looks completely different.

The explorer on our company computers still looked like the one from Windows 10. In Windows 11 it should have the tab function and has completely different menus and icons.

The problem was that we had a script running, whose purpose was to remove the bloatware from Windows 11 installation (Xbox crap, gaming apps etc....)

The script was designed to delete all apps except those I defined.
There is no App called "File Explorer" but there are a lot of libraries and other stuff and something seems to be related and needed by the new file explorer.

I disabled the script and instead, I specifically removed the apps we don't need directly from the Windows image so that they aren't installed at all.

Now the explorer looks and works as intended.

Maybe this helps somebody else, because a lot of companies have scripts running to remove the Windows 11 bloatware.
