1st you have to have HyperV Role installed

define the ImageManagementService Class as Variable

$Disk=Get-WmiObject Msvm_ImageManagementService -namespace “rootvirtualization” –computername .

Call mount method which require only the full path for your vhd drive like the example below:

$disk.mount(“C:Program FilesMicrosoft Learning50028BDrives50028-DC1-Data.vhd”)

once the command succeed you will see like new drive is being installed in your notification area

the problem now that the disk is currently offline like the disk 2 in the image below so we have to bring online and then assign Drive letter.

we can do this also by Powershell but it is very long I will add it later.
