So I'm having some trouble reinstalling windows xp pro on my laptop. I have two legal licensees - the one that came with the laptop (a Toshiba Satellite M55-S232) and one that I got through my school's MSDN program. I tried to install Vista Business on my laptop but it could not handle it so now I want to go back to XP Pro. I no longer have the CD that came with the MSDN purchase and I don't have any of the old Toshiba CDs (I bought the laptop in 2003). Anyway, I just want to know if I can do anything about this. Is there a real human that I can talk to at Microsoft that can help me with this? I own TWO copies. I should be able to install them even if I lost the CDs. Also, I should be able to get the CDs replaced at the least if I did lose them. Anybody have any experience with this?
