How to? Difference between REBOOT /P vs REBOOT /S ?

I would think that both options would log the user out and shutdown/turn off the computer.

I think there was a meaningful difference back in the Clinton administration, when not all computers could shut themselves off.

I may be imaging it, but I think you could actually use /s and turn the computer off manually if you wanted to for some reason back on windows 98, even if your computer supported ACPI.

I'm wondering if it has anything to do with the "fast startup" function that was introduced in Windows 8.
