This application allows up to four users with individual iTunes libraries to use iTunes on one computer, without having to log out of Windows to change users. Apple's iTunes software most easily accommodates only one iTunes profile per Windows user. Even the multi-library feature of iTunes is not convenient when multiple users wish to use iTunes without logging out of Windows to switch users. To the rescue, uniTunes easily keeps track of up to four users by maintaining a unique uniTunes profile for each user.
