FairUse4WM version 1.3 has been successful cracked and remove DRM protection from Zune DRM tracks. This mean you can play your legally purchased music on pretty much any device, not just Microsoft’s Zune.

FairUse4WM is a GUI version of drmdbg that supports individualization version .3930 and some WM11 versions.
Basic requirements
1. Does not work with Win98 or similar.
2. Works with both individualized content and some DRMv1 files
3. Supports WM9, WM10 and WM11beta1 and 2
The program’s functioning can be verified with “Demo” DRM files from fairuse4wm.com and ezdrm.com, as well as those from other Microsoft Solution partners.

The original post from Doom9 forum which the forum has listed several download locations and a short instruction on how to work with the drm stripper.

I not sure when this Zune crack software will be workable until when. But for sure Microsoft is working quickly to get an update out that will again make this unable to work.
