Remarks

Use this function to start or restart the specified Game OS from the cache on the console.

If you have a FourPartVersion for the Game OS you want to start, use the XtfStartTitleOSByVersion function instead to start that Game OS version. You can use the XtfGetCachedTitleOSVersions function to get the FourPartVersion of each Game OS cached on the console, or the XtfGetTitleOSFourPartVersion function to get the FourPartVersion of the Game OS for the currently running title. You can also use the XtfStartTitleOSByGameConfig function to start the Game OS identified in the specified contents of a MicrosoftGame.config file.

If needed, you can add a Game OS to the cache on the console by calling the XtfCacheTitleOS function.
