BSPlayer problems
 

After uninstalling BSPlayer from my computer (uninstalled WhenU as well), the option to "Play in BSPlayer" and "Enqueue in BSPlayer" remains in the menu when I right click any type of media file. How do I remove this?

You can try to do this in 3 ways:
1. Reinstall BSplayer, uncheck the option to associate it with all supported files and then uninstall it
2. Start another media player and associate those files to it
3. Remove those associations by editing Windows Registry

I suggest you the second option, fastest and with less problems.
The third is the worst one if you don't really know what are you going to do because you can crash your Operating System and then you'll ned to reinstall it or (if you can) restore it to a previously made restore-point
