Sometimes it is possible to find SID and KID for Windows Media files in the Internet (when content providers do not generate unique ones), but we strongly discourage you from doing that!

DRM removal software should only be used on LEGALLY purchased files to make fair use backups. Please do use it on rented or illegally downloaded files!

There are many good reasons to buy media:

• You help support an artist, a movie maker, ...
• Your media will be of the highest quality.
• You'll sleep better knowing you did the right thing.

I also suggest you to boycott any service that provides DRM protected content.
