For the record, I buy all the software that I use.
I've had a number of hardware and network problems with my XP Pro box in the past week, which has forced me to pull all my cards several times, repaor the OS, and eventually reformat and do a clean install. As I changed the hardware configuration, I was asked to re-activate on 4 separate occasions, which eventually sent me to microsoft.com looking for an explaination on what triggers activation. There's lots of information there, and including this FAQ:

Bottom line is that if you change your LAN card, reformat your hard drive, or change 3 or more of the 10 hardware properties that XP looks for, you will have to reactivate. As someone that changes their hardware configuration alot, this is going to be a nuisance.
In theory, as long as the OS is only on one machine at a time, Microsoft will continue re-activating you indefinitely. They were very courteous with me over the past week as I activated several times, but I'm wonderiong if at some point they give you a hard time about it and question whether you have the OS installed in more than one machine. Is there anyone out there that changes their hardware frequently and has been given a hard time by Microsoft on product activation?
