Disable fast startup from an Administrative template profile

Question

Hello,

In Intune I have create a configuration profile based on an Administrative template profile.
In the computer configuration list I have disable the setting "Require use of fast startup".

The configuration profile is assigned to a group who have a device has member.

The device status of the profile indicate that the policy is successfully applied.
But the fast startup is still enabled on the device.

For testing I also have enable the setting "Show hibernate in the power options menu" and the setting applied correctly on the device.

What is going wrong ?
Does I miss interpreting the setting "Require use of fast startup" ?

Thx

Jonathan

You are absolutelly right, using GPO or Intune admx templates will not disable startup, they will only enable it or set to not to configure. To disable Fast startup, you will need to alter registery, basically this:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power.
HiberbootEnabled (DWORD (32 bit))
HiberbootEnabled 0
