Windows Image to Virtual Hard Disk Converter (WIM2VHD)

WIM2VHD is a tool that will create a bootable VHD from a specified Windows 7 or 2008 R2 WIM image (like the INSTALL.WIM file that ships on the installation DVDs) without having to run Windows Setup.  That means that you can a Windows 7 or Windows Server 2008 R2 virtual machine up and running much, much faster.
