Windows Longhorn build 3713

This build is not much different from builds 3706 or 3718. It includes a working DCE, like build 3706 and 3718.

This build is basically the same as build 3706 in terms of functionality. However, the UI has been updated a little, including the introduction of the 'new taskbar' later used as the default one in Milestone 5 & 6. Notably, this is also the only Milestone 3 build that has both the Media Center Edition & the Tablet PC edition components. These combinations would be later seen in Longhorn Omega-13 (AKA Windows Vista) in the Ultimate SKU.
