delete it right now! Seriously uninstall it! It may be too late for you if you installed it though. WMP 11 contains very very bad DRM technology that will seriously mess up your operating system, it adds a bit of code into the operating system (Windows OS affected only) and make it even more difficult to play pirated music or music that it assumes to be pirated (regardless of whether its legit).
Install version 10 - it's much cleaner, and you'll still be able to play all your music and videos.
