Question: I am unable to delete, rename and even force delete (using /F in cmd.exe) a bunch of files. These were created during some updates etc and in a different drive than C root drive. Using Windows XP SP3. Any help, suggestions?

CMD.EXE gives error access is denied while deleting

Answer: 
The files might have strange permissions, and you might not be their owner.

See: [How to take ownership of a file or a folder in Windows XP](http://support.microsoft.com/kb/308421).
They are probably system level files that Windows is protecting. Windows (as far as I know) doesn't have a `sudo` *"I want this done and done now"* mode at all.
