How to remove Wmv Drm

I have some WMV files with drm protection that only allows them to be played on a certain amount of computers. My problem is that i am about to get a new computer but have used all the licenses, so unless i can remove the drm i wont be able to play the files anymore. Im having trouble understanding how to do this, so can someone please help me and guide me through the process starting with the tools that ill need.
