Hi,
I had a PSU failure on my Win 7 Desktop and it made WU inoperative, can't open Word files (missing access privileges) and killed shortcuts. I took a look at Tweaking and it couldn't get past the first Start Up Check test indicating missing files:

Are these issues that Tweaking can fix??
Boggin, in case you forgot, you helped me about 6mos ago under weird but similar circumstances. Tried to do a Windows disc install repair but kept failing. I finally got it to complete and it has been great since.... until.....
