any help is greatly appreciated

There are articles on how to assume ownership of directories. It is just a permissions issue. I would advise googling how to change permissions or just google for the actual error message it gives you.

Try right-clicking on the folder(s), ->Properties ->Security, then Edit and give all accounts possible "Full" permissions.

Sometimes it works, sometimes it doesn't - depends on how secure W7 is feeling today. Well, not really, but that's how it feels

Thanks for the answers but its still not working im just gonna put a linux partition on the drive a delete them from linux (hope the WUBI installer works on win 7),If linux ran games with out the problems i would drop this bloatware OS asap

Which folder(s) is it you're seeing? Windows 7 still uses older folders such as Documents and Settings so deleting it isn't wise - even if you did a format, this folder would still be there as it is used for something (not sure what but I'd guess support for older applications which aren't Windows 7/Vista compatable).

Just a thought, and too late, but could you delete the files by booting the computer off the Windows CD/DVD and using the repair console? (I haven't tried it.)
