Thanks for the reply. My english skills and the wording with the "from power menu" got me confused and I thought I had to do crazy stuff.The instruction is as follows:
"Simply, run Explorer and Task Manager in extended view (from Power Menu). Sort the view in Task Manager window by clicking the 'Name' column. In the Applications section, right-click on 'Windows Explorer' entry and choose 'Restart'."
Since it worked now I must have done it right. Open Eplorer (Windows Key + e) and (which I missed) open the taskmanager (crlt alt del) and restart the "Windows Explorer Task" via right click.
For me loging in and out for 30 seconds each exe was the annoying part. Now i know how to avoid the log in/out thingy and can decide if the exes or pathes suites me more.
Tldr: Thanks for the help again. Another thing learnd about H_C
