New Post: Show-InstallationRestartPrompt with no users logged in

Howdy. I need my app to reboot at the end of my script and I love Show-InstallationRestartPrompt for the "restart later" option; However, if no user is logged in, the reboot simply never happens. What's a better way to reboot a computer with no users logged in while still maintaining the Show-InstallationRestartPrompt for logged in users? Currently I use this:
Show-InstallationRestartPrompt -CountdownSeconds 500 -CountdownNoHideSeconds 120

Thanks!
