1903 changed Fast Startup settings??

Has the 1903 update removed the ability to disable Fast Startup?

Nope.

Why can't I see the Fast Startup option? I do not want Hibernation or pit the pc to sleep, is that why Fast Startup option does not show?

Press the Windows logo key + X on your keyboard and then select “Command Prompt (Admin)“.
At the command box type the following command and press Enter to enable hibernation:
powercfg /hibernate on
Close the Command Prompt window and then re-open the Control Panel. Fast Startup should be there now.

...or the command powercfg /h /type reduced which will not enable hibernation, but will return the option to turn Fast Startup on.

The command powercfg /h off disables both hibernation and Fast Startup.

No, it's the other way round. The option is missing from Control Panel because if there's no hiberfil.sys it's not possible to enable Fast Startup.

Thanks Grom0X,
I just wanted to ensure that Fast Startup was disabled but could not see the option>
That worked and I could verify that Fast Startup was disabled.

Thanks Bree, I guess that for what I want the powercfg /h off is the command for me!
