If you have been developing Windows 8 apps using Visual Studio 2012 Express and recently started working on Visual Studio 2012 Ultimate, it might take you few minutes to figure out where is "Suspend", "Resume", and "Suspend and Shutdown" option during debugging.
Because you may know that Visual Studio is a huge product and each express version is tailored as per its usage. So default toolbar of VS ultimate does not include this option enabled.
So all you have to do is to select "Debug Location" under View -> Toolbar -> Debug Location.
That's it. Now you can see the "Suspend" etc. option in toolbar.
