I searched all my os versions, I only have one file, & that won't correct your issue(s).
Give NoelDP a shout, of if you don't want to wait for him to reply, do repair install, that will definitely solve everything.
Takes few hours, updates take overnight.
If you have less than 8 gig RAM only install the first 100, or you get out of memory error.
I suspect that you're going to find a more problems along the way, but e can give it a go -
Please post the C:\Windows\windowsudpate.log file - with luck, it'll tell us why CheckSUR is failing. (It could simply be that some of the essential files for it are the ones affected by the corruption)
I also suspect that you'll have problems with a repair install at least until we get CheckSUR running, since it probably will also use the same routines.
