Can I unDRM WMV files if I am running Vista x64 SP1...

... With all the updates installed?

I got my computer yesterday and there wasn't any updates to install when I ran Microsoft Software Update. So it seems that my system is fully up to date.

I tried reading the FAQs, but I am new to Windows (and to Vista) and I found the FAQs to be a little confusing, especially because they keep linking to other pages, with newer / different information, etc.

I just don't want to waste my time on trying to unDRM my videos if it is not possible with all the software updates installed, running Vista x64 Ultimate.
