Hello,
Hyper-V manager GUI isn’t that fast and responsive, that’s event more true on Hyper-V home lab or on limited hardware host (yes, the ones we use for sandbox environment). So hereunder a PowerShell way to connect to VM with “VMCONNECT” without the GUI :
vmconnect HostName VMName
Then, you can go creative :
Get-VM | Select-Object -ExpandProperty Name | % {vmconnect $env:computername $_}
