I guess I have installed Windows XP Home on my computer too many times, and now I am not being allowed to "activate windows" (it says: According to our records the number of times you can activate windows with this product key has been exceeded.). That is quite possibly true, I have installed windows on my computer probably more than 20 times over the last 4 years (I do a fresh install before every semester, and have used Linux a few times). So, the question becomes, what should I do here? I am not going to spend $100+ to get another cd/key. And I really don't want to mess around with linux right now. I have been thinking about just re-installing every 30 days, but I hate having to download everything and set everything up again. Any ideas? Thanks! edit... I would probably be willing to use Linux (K/Ubuntu) if there was a way to play .m4a music files, and if the video support (.wmv and other extensions) were better supported (I don't want to rip all of my music again, and too many sites use .wmv for porn ). I have not used linux (Ubuntu) in probably 2 years, so maybe they have found ways to run these things by now?
