How to release it without ending the program

Windows Search is building its index. It releases the file by itself in a moment, so there is no need to end it.

If that still does not work

  1. Close the program and delete
  2. Unlock and delete
  3. Move to Recycle Bin
  4. Delete after restart

Get LetGoFile and drop the file on it — it names what is holding the file, PID and all.
