I was typing a genre for an album in WMP 12 when it decided to jump out of the field and now I have a genre in the drop down for "Roc". How do I get rid of this?
WMP keeps a "database" of all the songs / artists / genres / etc inside your profile folder. There are no (public) tools for accessing, or editing this database.
If you can afford to lose that database because of single spelling error, here is a Microsoft article how to do it.
Adding another user to your Windows takes about 10 mouse clicks, and 10 keystrokes.
If I log in on a new account everything is blank, including the music library (which I guess is limited to my original account?) Tried editing genre for a CD and there were no drop-downs at all.
