I was trying out a password program that I downloaded. After installation was through, Windows told me that some crucial Windows files had been replaced. It said that if I didn't insert the CD and restore them that Windows could be unstable. But then it wouldn't recognize my Windows XP Home CD. No harm seems to have been done... but should I do an Install/Repair from the CD to make sure that all the files are put back as Windows original? Also, another reason I'm asking is, I dodn't want PG to somehow be confused as to what is real and what isn't. I have the PG registered version on its way and I want all my Windows files to be native Windows. Am I being too uptight about nothing here? Thanks!
