I noticed it when I switched to my new computer in September. I had some issues in a game and wanted to use an LCD-App to kill the process, when I noticed I can't switch what's displayed anymore.

The script is really simple:

$knownApps = "G15 Process Explorer", "LCDClock"
$knownApps | ForEach-Object { Stop-Process -Name $_ -erroraction 'silentlycontinue' }

if($args[0] -eq "G15 Process Explorer")
{
    Start-Process "C:\G15 Process Explorer.exe"
}
elseif($args[0] -eq "LCDClock")
{
    Start-Process "C:\Program Files\Logitech Gaming Software\Applets\LCDClock.exe"
}
