        function New-OutOfProcRunspace {
            param($ProcessId)
 
            $ConnInfo = New-Object -TypeName System.Management.Automation.Runspaces.NamedPipeConnectionInfo -ArgumentList @($ProcessId)
            $DefaultType = [System.Management.Automation.Runspaces.TypeTable]::LoadDefaultTypeFiles()
 
            $Runspace = [System.Management.Automation.Runspaces.RunspaceFactory]::CreateRunspace($ConnInfo, $Host, $Default)
 
            $Runspace.Open()
            $Runspace
        }
 
        $PowerShell = Start-Process PWSH -ArgumentList @("-NoExit") -PassThru -WindowStyle Hidden
        $Runspace = New-OutOfProcRunspace -ProcessId $PowerShell.Id
        $Host.PushRunspace($Runspace)
}, "ALT+F5") | Out-Null
 
$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add("Switch to PowerShell 5", { 
    $Host.PopRunspace()
 
    $ChildProc = Get-CimInstance -ClassName win32_process | where {$_.ParentProcessId -eq $Pid}
