Possible to have Unity restart a PC? (Windows 8)

Here’s a puzzle –

I need a program (ie, a Unity build) to actually reboot the PC.

So, it’s just a normal Windows8.1 PC, running a Unity built app.

TBC there are no security concerns etc, this program (ie, the Unity build) is only used in-house. So the PC can be set up in any way needed.

I’m not much of a Windows sysadmin – can any one think of a way this could be possible??

Just FTR it would have to work cleanly w/ no stupid OK dialogs, etc.

Any thoughts? Cheers …

Not really a Unity related problem
