Tag AVD Personal Desktops With Assigned User

Here’s how you can use a scheduled GitHub Actions workflow to automatically tag virtual machines when users get assigned. This script will check all resource groups for HostPoolType equal to Personal and then tag each virtual machine with the assigned user. Tag Name= “AssignedUser” Value = “UPN”.
