Delete / Move / Unlock locked files by windows or other applications

I can't remember why I never posted about "Unlocker" the application, that is really good for unlocking files and folders being used by applications or Windows itself.

I had a folder that was created by windows during an update I'd presume or an install of something but the computer crashed and so the temp folder was never unlocked or deleted. Ran Unlocker for 5 seconds, couldn't find any application locking it but gave me the option to delete it, so i did. done!
