Using the Shut Down function in Windows shuts it down(turns it off). Punching the button puts it to sleep. That’s because too many people were accidentally hitting the button and losing everything. Holding the power button for several seconds will turn the computer off. Not recommended. Use the Shut Down function.
I am not talking about shutting down using the physical power button on the PC. I am talking about shutting down using windows shutdown.
Do you know that by default windows10 is not set to shut down when you ask it to. You have to go into settings(power options) and tell it to actually shut down when you ask it to shut down. However after sometime around the creators update it no longer does a full shut down even when set to do so.
