I knew this was coming: Microsoft is clamping down on piracy and illegitmate copies of their software via a new program called the Windows Genuine program.
In a nutshell, if your copy of Windows cannot be verified as unique, you will not be able to download MS updates and goodies. You will be able to access fixes, however, but everything else is off limits.
Just another tactic of Microsoft to squeeze every bit of profit they can out of their well-entrenched monopoly.
The Bad news.
