Windows 10: Random Users in User Folder

I have this problem, where i have random users over 50 of them in my User Folder. When i try to delete them, it tells me i need permission from "S-1-5-21-3270114583.... Basically just a random Administrator. I am the only user of this device. What can i do?*** moved to englisch Community ***

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.

 

Removing a "hidden" user and user files

Thanks for your patience. I was able with "Net User" to remove the left over user. It no longer appears when I invoke Net User.

Now for the user's folder which remains behind. After performing the series of steps that you suggested, I attempted to delete this folder. The result again was an error message about permission


"Administrators" appears on the list in the list of advanced security.

 

User's folder is not present in c:\\Users

Putting aside your somewhat random use of forward, backward, and double slashes, please explain the difference between:

• In Windows 7 Window Explorer, one cannot view the UserName folder
  in c:\\Users

and

• UserName folder, normally viewable from c://Users, can be still be viewed and fully accessed from UserName's Desktop
  via Window's Explorer

Click Start, type C:\Users into the Search box, and press Enter

Please list everything you see. If you would rather not reveal actual user names, use UserA, UserB, UserC, etc. Please mention whether view hidden files and folders is enabled or not.

Is the name of one (or more) users missing from the list of items?

Navigate to any document in the "UserName folder" that you can't see in C:\Users, then right-click and select Properties.

What is shown as the document's "Location"? Again, if you want to use UserA rather than the actual name, that's OK.
