Greetings --
Yes, certainly.
There's no limit to the number of times you can reinstall and
activate the same WinXP license on the same PC. If it's been more
than 120 days since you last activated that specific Product Key,
you'll most likely be able to activate via the Internet without
problem. If it's been less, you might have to make a 5 minute phone
call.
Here are the facts pertaining to activation:
