Hello,
soooo i just noticed, the User Files Folder, that can be displayed on the Desktop and Explorer
(you know, the one with your Username) has changed it's mind to Display "Ordner" (German for Folder*).
This is the case for:
- My Desktop User Folder Icon (See image)
- The Explorer Adress Bar, when opened*
- The Userfolder Preview Icon in the settings for Desktopsymbols
- The same things above for a New created test user
- Changing the System Language changed the Text to "Folders", wich means, that it's not something written in stone and it is translated somewhere
For some Reason, the folder is also found by Windows, when i enter the normal name of the folder.
(EDIT: No it's not. that was just a misinterpretation by me)
I already searched the Registery and found some entries for this folder, but when i compared them with a computer that does not has this issue, I did not found any differences, hence i didn't change anything.

(Not my username at all).
I'm currently running Windows 10 1803 Pro.
Unfortunately i recently cleaned the temporary files and,with it, all system restore points.
But there must be something wrong in the registery or Files it references i think.
