For the most part, your games and other programs should work just fine. One of the exceptions is if they are true DOS base games. These you might have a bit of a problem with. XP uses a DOS emulator and some software just doesn't like it. Hope this is what you are looking for, if not, post back. John.
I recently upgraded from win '98 to XP. Should my Microsoft '98 games,etc still work on my XP system?
