The action can't be completed because the file is open in Shell Infrastructure Host. But I don't know of any program that is installed on my laptop and has that name. What now please help
Check in the Task Manager whether you have this software open in the background (you can open the Task Manager via Control, Shift, Escape)
If you find this program, just exit it directly from the Task Manager
Unfortunately, I can't answer this question so quickly. Have a look here, maybe you will find a solution:
@ Etienne07 I can't find anything in the task manager under Shell Infrastructure Host
Mmh… You have Windows, right?
