I probably asked this before but I've been getting different opinions about it.

I have XP pro OEM, not a manufacturer OEM.

I have to do a repair install because I got a replacement Mobo under warranty.

I'll be using the original disk, processor, cdrom, nic card, same amount of memory.

Will it allow some hardware changes?

Should I expect activation problems?

If I get past the activation can I change the processor later?
