Windows 10 (like widnows 8 do) use a fast startup shutdown option wich causes many problems.
When you shot down windows 10 you will notice that when screen turns off, computer is still working and trying to shut down.
One problem is that if something goes worong (like an app that wont be unloaded) windows will turn on screen again (some times after minutes (!)) asking you to force shut down.
The reason that this is done, is because windows is trying to cache windows for next startup.This will allow windows to load faster next time.
But the truth is that there is no reason for using this feature (which i believe that would not be default in my opinion) since the time that windows will use to shut down is some times double that the time needed for normal startup.
How to Shut Down Windows 10 and 8 (Full Shutdown and Normal Hybrid Shutdown)
Create a Shutdown shortcut :
This is the recommended way, create a shortcut and whenever you want to shut down windows 10 in old way just run it.
Right click on desktop and select “New>shortcut”
On shortcut location type “shutdown /s /t 0” (without quotes).
Click Finish, and shortcut is ready!
From now on, every time you double click “Shut down” shortcut, Windows 10 will do a full shutdown.
Other way – Completely Disabling Hybrid Shutdown (or Fast Startup):
To do this, call up the Power Options program.
Start by typing “power” (without the quotes) in the start screen. This will bring up the Search panel on the start menu. Use your mouse to click the line that says “Power Options”.
The Power Options window will appear. Click the line “Choose what the power buttons do” on the left side of the screen. This will cause the System Settings window to appear.
Click the line “Change settings that are currently unavailable” under the top paragraph of that window.
When you do that, some new options will appear below. If your screen is small, you may not be able to see everything. If so, scroll down (eg by using the scroll bar on the right).
In the section with the heading “Shutdown settings”, you should be able to see 4 items. Click the box for “Turn on fast startup (recommended)” to uncheck it.
Click the “Save changes” button found at the bottom of the window. This will return you to the Power Options window.
Now click the “X” (close button) on the top right corner of the window to exit this program.
