I have a machine that I just reinstalled Windows and all of my applications onto... what a chore that is. I want to totally and completely avoid this from now on by creating an image.

My first thought was to see if it possible to copy a VHD file when you are booted into it since I am using Windows 7 Ultimate as boot-to-vhd (without a parent machine). Is this possible and if so, how could I accomplish this? Keep in mind, this is my personal machine and I'm trying to keep things inexpensive (a good script would work).

This question came from our site for system and network administrators.

Assuming you do not intend to mount a disk you want to boot of of (make a copy if you need to mount!) Microsoft/Sysinternals disk2vhd would let you convert disks to vhds, as the name states.

You can then boot this into a VM, boot off it with vhdboot, or mount the VHD (on another system preferably!) to copy files off it.

Microsoft TechNet strongly cautions against trying this.

Do not copy a .vhd file while it is in use by a virtual machine. The file system of the host operating system does not prevent you from copying a file in use; however, data will be missing from the copied file because data in the virtual machine's memory will not be copied. Do not copy a .vhd file that is used by a virtual machine configured as a domain controller; doing so can cause problems such as duplicate security IDs (SIDs) appearing on the network.
