WGA Cracked

Microsoft Corporation requires users of it's flagship operating system,
Windows XP, to verify the authenticity of their software installation
before downloading patches and updates from Microsoft's website. The
validation tool, called Windows Genuine Advantage (WGA), can easily be
cracked without much trouble. This allows users of pirated copies of
Microsoft Windows to verify their installation and receive the extra
bennies offered from the manufacturer.

Although Microsoft has not confirmed that the crack works, details are well
publicized, and it appears that the crack is popular, at least amongst
nefarious users.

Previously, JavaScript tricks were required to bypass the WGA requirement;
however, now it appears that it's as simple as running the WGA application
in Windows 2000 compatibility mode.
