Disk2VHD is a practical free tool by Sysinternals, since 2006 a subsidiary of Microsoft Corporation. Sysinternals is well known of their wide range of free tools to manage, troubleshoot and diagnose Windows systems and applications. As the name already tells Disk2VHD is a tool to create a Virtual Hard Disk (VHD) file of an existing Windows system. This VHDfile can then be used to create a virtual machine in Windows Virtual PC (Windows 7) and Hyper-V (Windows 8 and later).

In this tutorial we will download and install Disk2VHD on an existing Windows 10 computer, use it to create a VHD of the current Windows 10 installation on that computer and use the resulting VHD to create a virtual machine on Windows 10 Hyper-V. The virtual machine will be an exact copy of the original Windows installation apart of some hardware and drivers, Hyper-V replacing some hardware with its own virtual devices.

The virtual machine will be fully functional and contain all software, user profiles and settings which were installed and present on the real physical computer and Windows when the VHD creation process was started.
