I needed to delete a ton of test VMs and I really didn't want to right click on each VM and delete.  Here's a quick script I used to delete them quickly!  1 line for each VM as you can see.

 

---------------------------------------

Remove-VM -VM TEST2K8R2-05 -DeletePermanently -Confirm:$false

Remove-VM -VM TEST2K8R2-06 -DeletePermanently -Confirm:$false

Remove-VM -VM TEST2K8R2-07 -DeletePermanently -Confirm:$false

Remove-VM -VM TEST2K8R2-08 -DeletePermanently -Confirm:$false

Remove-VM -VM TEST2K8R2-09 -DeletePermanently -Confirm:$false
