The next version of Windows Home Server codename “Vail” has been leaked online. This version of WHS is based on Windows Server 2008 R2, unlike the previous version which was based on WS2003 code. As a result, UI has got a significant facelift and it now looks more or less like Windows 7 because of the “Desktop Experience” of WS2008R2, which is installed and enabled by default on WHS “Vail”.
