Pirates Exploit a weakness in Microsoft’s Key Management Service (KMS) To Get Windows 8 Pro Free Copies: When a better lock’s built, folks just devise new ways to pick it. It’s
pretty much a fact of life. So it’s not surprising that folks have
already pirated Windows 8. If anything, it was probably expected. What is surprising, however, is that Microsoft’s just unintentionally legitimized pirated copies of Windows 8 Pro through a Windows Media Center upgrade.
The Media Center upgrade, which Microsoft is offering through January
31, 2013, includes Microsoft’s tools for watching and recording live TV.
However, applying the upgrade has an unintended side effect: It
permanently activates the copy of Windows 8 that you’ve applied it to.
Exploit allows all those pirates currently using the KMS exploit to
suddenly grant themselves a complete copy. Since KMS installs basically
expire after 180 days .
