Restarting a PowerShell script after the last process is closed

I wrote a script, which opens 7 programs approximately 10 times (yes its a prankscript).

My question is, is there a way to observe, if the last process is closed and if so, restarting the whole script again?

while ($start -le 10){  Start-Process mspaint.exe  Start-Process notepad.exe  Start-Process write.exe  Start-Process cmd.exe  Start-Process explorer.exe  Start-Process control.exe  Start-Process calc.exe  $start =+ 1}

My script now looks like following:

$start; $processPowerShell.exe -windowstyle hidden { script.ps1 }while ($start -le 10){    Start-Process mspaint.exe    Start-Process notepad.exe    Start-Process write.exe    Start-Process cmd.exe    Start-Process explorer.exe    Start-Process control.exe    Start-Process calc.exe    $start =+ 1}$process = Get-Process mspaint.exeif ($process = $false){    Start-Process -FilePath c:/script.ps1}

I did test this, but it starts all over again... I think that I use Get-Process wrong...

Is there another way to observe, if the process is closed or not?
