My friend asked me to fix his (corporate) PC for him. It has Windows XP installed on it and he doesn't have the install disc anymore, so I can't really format and reinstall it.
What are some other steps I can take without reformating the PC? It basically works, but is just slow. He'll be giving it to another member of the corporation.
What I've done so far is that I've removed all user accounts completely and created a new, fresh user account for the new owner. I'm wondering whether there's anything more I can do.
