It's an issue on a Win7-system.
It looks like system-Process (PID 4) (running ntoskrnl.exe) doesn't releases handles on *.exe files after the programs are closed.
Hence, those files can't be deleted, it's impossible to update any program.
I looked onto with the ProcessHacker or sysinternals Processexplorer (both in Admin-Environment) and no process of the *.exe are running for several minutes. But system has still an open handle to that *.exe. Trying to close that handle out of either of that tools is not possible. As I try to close that handle in Processexplorer, I get an pop-up message telling "Error opening process: The handle is invalid."
Hence, all options to delete the *.exe manually (Explorer, cmd, Powershell) don't work at all.
I checked the system (sfc command), no issues.
I tried the mentioned solution in Windows 7 access denied to executables.. by what? and had no success. Could the thumbs.db cache disabling really influence that ? I didn't tried yet the over-there mentioned answer.
How to fix that / release those handles without a restart ?
