I had to reinstall windows xp because I could not escape the blue screen of death after a virus infected my computer. After reinstalling, I initially had a problem of not being able to log in, but this was fixed after I got some help from this site. But now I have a different problem. I cannot activate windows xp. According to the Microsoft directions you have to go to system tools and click "Activate Windows". However, when I do that I do not see "Activate windows". When I click the bubble warning me I only have 29 days click here to activate, the hourglass shows up for a second before disappearing; nothing happens after that. How am I supposed to activate windows?
