Disable Fast Startup Power Management option via GPO

[Geoff]

I need to be able to disable 'fast startup' in Power Options -> System settings. I have the Win10 ADMX templates in my policy store but I can't see an option to disable it (when I apply my current Win 10 Power Management GPO the option is greyed out and enabled). I have disabled the hibernation options but that doesn't seem to of helped. Has anyone any idea how to do this?

For anyone from google who stumbles across this in the future. I created a group policy preference in the computer configuration to replace the registry key involved. The details are:

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power

 

HiberbootEnabled DWORD

 

0 = Turn off fast startup

1 = Turn on fast startup
