It seems a simple hack or crack is too simple
http://www.pcworld.com/article/id,128115-c,hackers/article.htmlHackers are distributing a file that they say lets users of the corporate version of Microsoft's Windows Vista operating system get around the software's anti-piracy mechanisms.
Windows Vista must be "activated," or authorized by Microsoft, before it will work on a particular machine. To simplify the task of activating many copies of Vista, Microsoft offers corporate users special tools, among them Key Management Service (KMS), which allows a company to run a Microsoft-supplied authorization server on its own network and activate Vista without contacting Microsoft for each copy.
The software Microsoft.Windows.Vista.Local.Activation.Server-MelindaGates lets users spoof that KMS process, allowing them to activate copies of the enterprise editions of Vista, its creators say. The hacked download is available online on sites including The Pirate Bay and other file sharing sites.
The MelindaGates hack allows users to download a VMware image of a KMS server which activates Windows Vista Business/Enterprise edition, its creators claim.
The endless battle rages on but to what purpose, who really wants a souped up XP with more rights stealing features that only lead to the road of you no longer being in control of your machine.
