Have you ever been in a situation where you just want to chill and scroll through Instagram, Reddit or Facebook at work, but your silly MS Teams, Skype or whatever switches to Idle status after a few minutes? Here's the solution! This PowerShell script will press the CTRL key every 5 minutes for you and prevents these apps switching your online status.

Code:
cls
Write-Host"Anti-AFK-Script"
$wshell = New-Object -ComObject wscript.shell;
$i = 0
$intervall = 300
While($True) {
  $i++
  Write-Progress -Activity "Next key hit" -SecondsRemaining ($intervall-$i) -Status " "
  $host.ui.RawUI.WindowTitle = "$($intervall-$i) seconds left..."
  if($i -eq $intervall) {
    $wshell.SendKeys('^')
    $i = 0
  }
  Sleep 1
}
Create a new file on your computer, for example "anti-afk.ps1", open it with a text editor and copy&paste the code in. Save the file, rightclick on it and select "Run with PowerShell". Done! :-)
Note: At the first run, PowerShell might ask you if you really want to execute the script (Windows default security settings...). You should of course select Yes here.
