In an undisclosed policy change, Microsoft is now allowing owners of its Xbox One console to change their ‘home’ console up to 5 times per year. Previously, the home console could only be set 3 times per year.
Setting a home Xbox designates which console automatically downloads purchased content from the Xbox Store, as well as the console which shares games and Xbox Live Gold.

While a small change, it is likely welcomed by those who switch their home console often – such as between friends or when moving around.
