In an attempt to get Musicmatch Jukebox users and owners to upgrade to Yahoo Music Jukebox, Yahoo used the Musicmatch Update software to add a nagware screen to the existing Musicmatch install. This screen was installed for Musicmatch 9 and 10 users whether or not they checked the "Check for upgrades" box in programs setting. When Yahoo modified the Musicmatch installation, it would nag to upgrade by September 2007 every time the program ran. On installs with this nagware activated, this screen continued to appear, even though September 2007 is well past and Yahoo has dropped the entire product line.
