Hi flourno6 ... and welcome to the forums ...
We have techs in the Windows Update forum that have special training (and quite a lot of experience) in fixing SFC corruption issues. I'm not a moderator, so I can't move your post there - but you can open a new thread in that forum. They have a very good rate of success. Good luck!
