    Write-Host "The screen will remain active for $minutes minutes."

    $wshell = New-Object -ComObject Wscript.Shell

    for ($i = 0; $i -lt $minutes; $i++) {

        Write-Host "The screen will be active for another $($minutes - $i) minutes."

        Start-Sleep -Seconds 60

        $wshell.SendKeys("{NUMLOCK}{NUMLOCK}")

    }
