Its your preference folder (it doesn't get deleted when you uninstall Maya so that won't change a thing) You can access your prefs fast by clicking the animation prefs down in the bottom right corner, under 'Category' choose 'Interface' and make sure 'In main window' is checked


Edit: like a dork I forgot to add

You can access prefs through the hotbox duh /smacks head
Windows>Settings/Preferences>Preferences
