Microsoft has issued a number of new nonsecurity updates on Windows Update and the Microsoft Download Center, most of which are for the latest versions of the client and server operating systems.
The first release is for a game, application, or firmware that is installed incorrectly, causes system instability or has primary functions that do not function properly.
Media Center fixes
The first Windows Media Center update is the February 2010 Cumulative Update, improving the Win 7 experience for those with digital cable card tuners, and resolving some compatibility issues for some legacy Windows Media Center extensibility applications.
