Sometimes you might need to copy files from a Hyper-V Virtual Machine or Guest to the Hyper-V Host.
PowerShell can easily help you with that. Just use the -VMName parameter with the New-PSSession cmdlet on the Hyper-V Host to create a new session to the Hyper-V VM and store it in a variable. Provide credentials for the VM if needed.
$session = New-PSSession -VMName "vmname" -Credential (Get-Credential)
Then use the stored session with the -FromSession parameter with the Copy-Item cmdlet and copy your file(s) from the VM to the Host.
Copy-Item -FromSession $session -Path "C:\path_on_vm\*" -Destination "C:\path_on_host\"
Using -ToSession gives you a solutions to copy files the other way round: from the Host to the VM.
