I have every intent on answering this myself in case of the statistically unlikely event that someone else has this problem... – Austin Salonen Sep 4 '09 at 21:00
i like the way you state your intent - you do realize that the world has 6 billion people, and over a billion PC users right? "Statistically unlikely"? 5.5 million results on Google for this "statistically unlikely" event. – caliban Sep 4 '09 at 21:04
I was amazed we still had files around that hadn't been edited in at least 10 years and were still necessary. With the frequency of getting new machines in the late 90s/early 2000s, it's amazing they made it through untouched. – Austin Salonen Sep 4 '09 at 21:31

Run the registry scripts from KB 938810. There is a restore script when you've completed your PP95 conversion.
