Windows XP activation

[kputer]

I've heard that MS will require Windows to be registered to get updates sometime this summer. Anyway, I am trying to find the cheapest way to legally own the Windows I have on my pc's. I see a huge difference in price for the OEM versions versus the Retail. For example; is the Dell OEM version I buy on Ebay legal to put on my pc that I built? I'm not looking for MS support, I know OEM means it stays with that pc. I have a working copy of XP w/SP2 so I really don't even need the cd. I know how to change the cd key so I wouldn't have to re-install. I just need evidence that I own it and I can register and get updates later this year. Could anyone please advise me on the best way to make my pc's legal?
Thanks,
Kputer

You can install OEM versions on any box. You can only have it installed on one box at a time. Best bet is to buy the update version instead of the full version. It is cheaper. As long as you have a copy of 95, 98, ME or 2000 Pro to use on install you'll be ok. You can still only have it installed on one box at a time.
