Fast startup settings come into play only when you are shutting down the computer and not when you are restarting it. The answer is, in a way – Yes! But Windows will reinitialize itself automatically whenever needed and whenever a system or hardware change is effected – and whenever it is required.
How to Full shutdown Windows 11/10
But there may be times where you may want to perform a complete, hard, or full shutdown manually. For instance, if you have added or changed some hardware, you may want to force a full shutdown. The Windows UI offers an option to revert back to the old Windows full shutdown or cold boot behavior, by unchecking the option Turn on fast startup (recommended). Choosing Restart from the UI will do a full shutdown, followed by a cold boot. Alternatively – Microsoft says that you can use the new /full switch on shutdown.exe. But I see no such switch for CMD on my Windows PC. What you can do is, open the command prompt (admin), type the following command, and hit Enter: This will make your Windows 11/10 computer shutdown ‘fully’. The correct syntax thus for a full shutdown of Windows 11/10 should be: shutdown /s /f /t 0 and for Hybrid shutdown should be: shutdown /s /hybrid /t 0. Hope this helps!
