FairUse4WM is a GUI version of drmdbg.
FairUse4WM 1.3 fix-2 supports Windows Media Player 9,10, and WMP 11 Final with version 11.0.6000.6324 and lower.

Basic requirements:
1. Only works on individualized DRM file
2. Requires Windows Media Player 9, 10 or 11 (doesn't work with WMP 11 with versions higher than 11.0.6000.6324). Works on Windows XP, Vista x32/x64
3. Works with both individualized content and some DRMv1 files
4. Does not work with Win98 or similar.

The program's functioning can be verified by stripping DRM protection from Demo files from ezdrm.com, as well as those from other Microsoft Solution partners.

Limitations
This program is ONLY designed and intended to enable fair-use rights to PURCHASED media.
- While the developer haven't been able to support license expiration/rental detection, please don't use this to abuse rental license
- This code does NOT allow import of KID/SID pairs to preclude its use for piracy

Note that some WM installations will have multiple ECC key-pairs, so you will likely have to "Extract Keys" using multiple licensed files. If you find a file that doesn't convert, try extracting keys wth it. Once your whole set of keys is extracted, you will no longer need to run WM per file.

We've tested FairUse4WM and can confirm that it quickly and easily strip the DRM protection from online music services like Napster and Yahoo! Music Unlimited. fu4wm can strip DRM protection from PlaysForSure media services. And this lossless DRM removing allows you to make your Windows Media files playable after you're no longer paying fees on your music subscription service.
But I repeat again: Please do not abuse rental licenses. Use drm removal software on LEGALLY purchased files only!

p.s. Please use FairUse4WM to create fair use backups only.
