With virtualization you can run an operating system within another. There are plenty of reasons why you would want to do this: you can test out software, products and suspicious files in an isolated environment without damaging your host operating system.
Disk2vhd allows you to create a Virtual Hard Drive (VHD) of a physical machine even while the machine is up and running using volume snapshot technology. This small utility doesn’t require installation and you can run it from a flash drive if you want. Just open up the Disk2vhd folder and run the executable.
