Microsoft Windows XP Professional w/ Service Pack 3 Untouched Retail keyless
just use WPA, WGA Fix's and your all set no need to enter a product key. I extracted this genuine retail copy of XP into a folder and intergrated SP3 that's it no other modifications.
P.S. This is 100% genuine retail copy with service pack 3 included, I intergrated the service pack 3 from a CD-ROM Microsoft sent me via snail mail. Again everything is 100% genuine and untouched download and you will see.
