Hyper-V - Create VM powershell script
Hi, Powershell script to create a VM after prompting the user for various settings. The script then attaches an ISO which is a boot media for an MDT server that is built tp push a particular task sequence resulting in a failry automated VM deployment. I normally do this type of stuff with VMM etc but the client only has Hyper-V and wanted it automated as much as possible.
