Blogpost - Create Hyper-V VM and enroll it in Autopilot automatically

Wrote a blog post on how to create a VM and register it for Autopilot automatically (https://powershellisfun.com/2022/08/25/deploy-a-hyper-v-vm-and-register-it-for-autopilot-automatically-using-powershell/) Below is the script that I created for it, please read the article about how to create the intune.iso and App registration that is needed for this to work.

#Requires -RunAsAdministrator
