Attach VHD (Windows 7 and Windows 8)

"New features in Windows 7 and Windows Server 2008 R2 allow Windows Admins to create, mount, and attach virtual hard disks (VHD). This feature will get a lot of use from Windows admins and it saves us from having to use 3rd party tools to do this. In fact, Microsoft is even offering test drives of their popular enterprise applications (such as Window 7 and Exchange 2010)."
