Disk2vhd is a free utility from Microsoft that allows users to create a complete copy of their physical hard drive in a virtual hard drive (VHD) format. It enables users to migrate a physical computer system to a virtual one, or to create a backup of their physical system. The utility works by creating a snapshot of the source disk and then copying the contents of the snapshot to the destination VHD. The resulting VHD can then be used with Microsoft's Virtual PC or Microsoft Hyper-V virtualization solutions. Disk2vhd supports both Windows XP and Windows Server 2003 operating systems, as well as Windows Vista and Windows Server 2008. Additionally, the utility can also create a VHD from a physical Linux system.
Discontinued The program is no longer updated. The latest version, 2.7.9, released in May 2011, can still be downloaded from the official website.
