While I was in my Windows 2000 server class on 2002, we passed around a disk with a keygen for XP. It may or may not have been cracked, but it generated keys for years, until activation could be bypassed.<p>The actual crack came more then a decade later, first as a web app, then as sample code. These guys just repackaged it.<p>And yes, Windows XP still lives on as Windows XP integral edition. Update all your certs from DER files, not from some fancy app.<p>Thanks to avaxhome, HiRens and studioXX.
