“I’ve found an even easier way to do this.  I found a PowerShell Hyper-V script at:

http://www.codeplex.com/PSHyperv

It has a lot of functions already, and I added a “Kill-VM” function that automates the kill process:

Kill-VM <VM name>

My modified script is attached to this message.

To use it, you need to install PowerShell (Under Server Manager -> Features in Win2008).  Once installed, run PowerShell from Start -> Search, find the script, and type:

. .hyperv.ps1

Once loaded into memory, type:

Kill-VM <VM Name>

Enjoy”
