Hello,mate,I am using vista os, can I back up my key of DRM?

I read your post of how to back up key of DRM protected video, but my computer uses vista which cannot install WMP10, do you have other method to back up key?

thanks~!!!

[I hate GGGZ file]

WMP7,8,9 or 10 you can back up key by just tool, key manager and back up, but you can not do that with WMP11.

And you can not install WMP7,8,9 or 10 under vista OS!!

Microsoft say WMP11 is still a beta version....

However, I can still play it by WMP11, I heard there are software you can use to remove protection of the video if you are able to play it, can anyone tell me what software it is?

Thanks~!
