Windows XP Restore Points

Windows XP’s restore points have saved me loads of time in troubleshooting problems with my Dad’s computer. Rolled the thing back to when I last had it and it’s fine… I’m thinking the problem is with an old version of Printmaster Deluxe which my Dad installed. (It is old enough that it didn’t show in Add / Remove Programs.)

I’m thinking that it overwrote some Windows files somehow, and Windows File Protection, for some reason, didn’t do its thing. That somehow messed up the machine, it started running slow, etc. I’ll test this tomorrow (or whenever I return the machine) by setting a restore point, installing the questionable app, inspecting things, then rolling back to the previous point if needed.
