I installed XP Home a couple of months ago and probably because I mess around and do some stupid things, I have lost the ability to do some things, such as, going to Start, Programs; when I place the cursor on the list of programs and right click, nothing happens. So, I can't delete or rename or sourt, etc. I think something is screwed up in the registry. What would happen if I just stuck the XP CD in the computer and re-installed it? Thanks!
