Holger, GM OM. Yes, it is still GM here at -28.9 ø C.  Brrr !   
      
   	Obtaining a 2nd hand machine always leads to problems of sorts. Cleaning it   
   up of redundant files, loaded by a non educated user is the problem.   
      
   	In your case, can I suggest to first make a clone of it all, then go to that   
   little start window on the left of the taskbar, one click on it -> Settings ->   
   Update & Recovery -> Recovery -> Reset this PC.   
      
   	This will do the job in one swoop. It will reset it all to a blank W-10 OS   
   machine, you might even get the choice of language, worth a try ! Read all the   
   instructions as they are presented to you, there are many a choice to pick. Do   
   anything to the machine, you have a clone ! Not ?   
      
   	Remember that a clone will allow you to, after the fact, move any file/folder   
   back from clone to main machine. I abuse this privilege all the time, even   
   from clone to another machine, not the source.   
      
   	We are having fun !  All fine wishes.
