CPU upgrade and Windows XP

[Shepp]

I have been kicking around the idea of upgrading the CPU on my PC. I have Windows XP SP1 and was wondering if such an upgrade will be a problem with the activation. Has anyone here had any experience with this?

nope, dont worry about it.

doubtful if that's the only change you make, but even if you do have to reactivate it's not a big deal:

What if I make too many changes?

If, on Windows startup, there are not the required seven Yes votes, the system will, in the original version of Windows XP, only boot to Safe Mode. You will be required to reactivate by a phone call to Microsoft. You will have to write down a 50-digit number, call into the activation center on a toll-free number that will be given to you, read and check back the number you recorded — and explain the circumstances. In exchange, you will be given a 42-digit number to type in. This will reactivate your copy of Windows.

This is made easier if Windows XP Service Pack 1 has been installed: The system will continue to boot normally for three days, during which time you will be able to contact the activation center via the net. If the extra changes have been removed, or if 120 days have passed since the original activation, you will be able to use the automatic process once more
