Not looking for any mac or linux etc comments. On topic. Went to visit my folks, the laptop they have was slow and just in need of a format. Formatted it, reinstalled windows. Everything was working fine. Updated to SP3, and now it is saying the CD key needs to be activated (again). But it won't confirm the key. Acting like it isnt legit. (It's a Sony Vaio laptop with a legit XP cd key and sticker thing attached to the bottom of the laptop). Anyone have any suggestions? I know there are ways to bypass the activation key, but I would rather keep everything legit. Any ideas?
