Windows Defender Beta 2 will add support for Outlook, a new interface, and automated updates to the spyware definitions and scanning engine. Where Beta 1 has been available only for Windows XP, Beta 2 will run on other Windows versions.
Windows Defender, Microsoft's free anti-spyware program that's been in beta for more than a year, will shift into its second round of testing in the next two months, developers for the Redmond, Wash. company said recently in an online chat. Defender is the new brand name for what Microsoft still calls Windows AntiSpyware, the add-on that's been in Beta 1 since it debuted more than a year ago. Beta 1 only works in Windows XP.
Windows Defender Beta 2, on the other hand, will be available for Windows 2000, Windows XP, Windows Server 2003, and Windows Vista, with additional editions for earlier Windows posted at some undisclosed future date. It will be included with both the client and server versions of Vista, Microsoft's next operating system, which is to unveil late in 2006.

Awsome, WSUS support!
If you don't pass validation then you don't own Windows.
64-bit will replace 32-bit, why would they not make it work for 64-bit Windows?
Good thing I didn't know it wouldn't work on them!
should have checked the ms website for the system requirments.
it works on win2k, and server 2k3 aswell.
thats personal experience as well...
Shows they don't give a toss about trying to make their products more secure. They'd rather make Ultimate Editions of Vista with themes and games and pinball crap and charge the earth for it.
not just XP
I know people that have invaild cd keys and are still able to download updates.
Are there certain updates that are downloadable without WGA, or did they find a way around WGA?
For example, Microsoft .NET Framework Version 2.0 Redistributable Package (x86) download doesn't require WGA
