Delete.On.Reboot is a simple but powerful option for deleting non-erasable files, directories, subfolders upon Windows restart.
This tiny app will be useful when standard deletion methods fail. Unlike the aggressive approach of deleting locked files provided by ThisIsMyFile, this method is the regular procedure; supplied by Microsoft on all Windows OS, but here you can still also move the files to a directory, for example, to check the possible culprits' files.
Delete.On.Reboot additionally provides a security warning if you attempt to delete any files and folders, which may cause your system to crash, allowing you to verify the file before you remove it.
