Help!! Can't load XP service pack 1

I bought a small bussiness with a computer but it has one of the reg keys that are blocked ( 0065 or something) how do I get by this and download it.

 

You want to download the entire thing?

No it already has Windows XP professional but its an illegal version.

 

The link I gave you is for SP1a, but I don't know if it will install on an illegal copy of XP.

 

Pretty simple, really.

Buy a legal version of XP.

Your product key is blacklisted, your license is not legal.

This makes you ineligible for use of Service Packs and the Windows Update site.
