I had to recreate a vm often with a virtual hard disk, because exporting a vm was quite long
So i started storing my virtual disk on a removable usb3 drive
Since hyperv is a service, I needed to recreate the vm on any computer to work with
Only the hard disk was important to restart the vm on another computer quickly
I found code in powershell on internet and adapted it to my needs
I added powershell code references at the end for futur use
2019-08-03 added the state of hyper-v service
