Hi again GoodGuyChuck,
Did you try running the chkdsk?
If you haven't already please can you try creating a new Windows User Profile(with admin rights) to see if this changes the situation at all. You can try this as well distiny.
Due to a huge number of setups and conflicts that can occur, files can very easily become corrupted during the patching process, due to hardware or software issues.
Thanks for your patience.
Making a new account changes nothing, chkdsk showed no errors.
