Also, The ONLY thing that worked for was this.

1. I went into the C:\Windows\Temp directory as an administrator and made a copy.
2. Then deleted all of the items in this directory (About four items were still in use).
3. Then went back to Windows Update and got the windows update from Microsoft Update / Windows Update (Rather than WSUS).
4. Installed all the updates that I needed.
