I tend to just check uptime before asking this question.

If I see the machine has been up for weeks and they tell me they rebooted it, I know i’m dealing with someone who doesn’t know that pressing the power button on the monitor doesn’t turn the computer off.

Could also be windows fault.

It likes to do soft restarts and not actually restart.

I started telling my users to always hold shift when shutting down or restarting to make sure it shuts down fully.

I explain fast boot to people by saying “for some reason Microsoft went and made the Shut Down button not actually shut down your PC, it really just puts it into a ‘deep sleep’ mode, and to their credit, it lets them say that boot times are faster… But it also means that in order to FULLY restart the PC, you have to click restart… I know it’s a pain”

Usually I get looked at like I’m from another planet, but that reaction means they’ll probably remember it later.
