Windows 8 has come out with some amazing power saving, time-saving, resource saving ideas and one of them is both saving power and memory when not using the metro apps in Windows 8. I thought that it was fantastic that the Metro apps could be suspended when they are no longer visible to the user, therefore conserving our CPU resources and saving power. But then I saw this interesting article on the Microsoft blog which added even more savings to these idle Metro apps.
Whenever Windows detects memory pressure on the system, it will repurpose nearly all the memory that suspended Metro style apps would otherwise hold onto. Windows 8 can reclaim this memory without having to terminate an app.
This is an awesome feature and you can see it all in action in the video below.
So when Windows starts to run low on available memory, the Windows 8 operating system will look around for memory that it can re-purpose to satisfy the other applications that need the memory now.
