I have a problem on my PC. It happens quite often, that I want to update some kind of software (e.g. games with some kind of launcher who updates the game or even a normal update via MSI. Yesterday it was "Anti-Malware Bytes" and before it was the updater of Aion.) and the update fails, because the updater can't overwrite/delete some exe files. Sometimes it works after a few tries. I am not able to delete the files manually, too, same error, but I couldn't find any process that is still running. Uninstalling throws the same error. Booting in safe mode and deleting the file there worked.
I've already checked the PC with a live-cd virus scanner, a normal virus scanner and anti-malware bytes. No results.
The user is of course an administrator.
Any ideas except reinstalling windows?
