PLEASE!! their is that better moderator.

I think this was answered in your first thread.

I believe the link you were provided with previously was this one:-

Windows 7 – How to Delete Files Protected by TrustedInstaller

Did this assist you in any way?

In your media library did you select the entirety of C: drive as a folder?

well it seems to be fine now except for the cpu useage at 100% of one processor some times so thanks for the help. any idea why im useing so much of my cpu??

I'm sure I posted in a thread with a link, did you delete the thread? O.o

Have you checked the MSCONFIG, and checked which programs are running at startup within the Startup tab?

I posted that link.

I concur.
