One of the most useful computer networking apps on the Windows Store is Remote Desktop, which allows you to remotely connect a Windows 8 or Windows RT to a remote PC. Unlike typical TCP/IP network connections that enable you to do things like instant message, or share files via Windows Explorer, remote desktop connections give you a full screen graphical view of the remote computer's display. They also allow you to interact with the remote PC via keyboard, mouse and sometimes touch as if you were using it locally.
