Such is life. When i got it home and turned it on there it was again, .net v. 3.0. I un-installed the latest update and that wasn't it. So I went into the windows folder and found the culprit, took ownership, it said after I tried to delete it that I needed permission from the trusted installer, whatever that is. By taking ownership I was able to delete it. Now my cpu is back to normal. The tool didn't work either. Go figure.
