By default, Windows 10 enables a feature called Fast Startup (Hybrid Shutdown) that can shut down and boot up your PC much faster than Windows 7 or previous versions of Windows. When you shutdown Windows 10, you’re actually performing a partial hibernation.
Method 1: Perform a Full Shutdown Using Command Prompt
Just open an elevated Command Prompt or PowerShell window, type the following command and press Enter:
shutdown /s /f /t 0
This will immediately close any open applications without prompting to save your work, and completely shut down your PC.
Method 2: Perform a Full Shutdown Using Shift Key
We’ve covered many different ways to shutdown Windows 10 in the past, but you might not realize that Windows 10 is just doing a hybird shutdown by default. If you would like to perform a full shutdown, simply hold down the SHIFT key on your keyboard and then click the “Shut down” option in the Start Menu, or on the sign-in screen.
The Fast Startup feature can make your computer boot up faster, saving valuable seconds every time you turn on Windows 10. However, if your Windows 10 was installed on a speedy solid-state drive (SSD), Fast Startup don’t actually make any difference and a full shutdown is recommended.
