One thing mouse-and-keyboard users miss a lot in Windows 8.1 is use of the traditional Desktop view and all its functionality. Here you see the newly updated Desktop. Note the aqua mountain-skyline with sun icon in the taskbar, which denotes the Photo app. It is a Metro app (now known as a Windows Store app), and in the previous version of Windows 8.1 such apps could not be pinned to the task bar. Now they can, making them easier to find for traditional Windows users who use the Desktop as their center of operations. The taskbar displays both pinned apps and all open apps.
