How to enable hibernation on a Guarded Host running Windows 10 Fall Creators Update

The Guarded Host feature (pictured below) allows us to run shielded VMs on Hyper-V with remote attestation. While uncommon on Windows 10, it can come up both in lab testing and developer scenarios in ultra-secure environments. In this case, a user noticed hibernation was disabled once the Guarded Host feature was enabled.  What’s more, it would not come back through changing the normal settings.

I assume this may not have been true on previous versions of Windows 10, as in this case, Guarded Host was in use for some time on previous Wndows 10 builds.

The fix
It turns out there is a setting in the registry that appears to be added when you enable the Guarded Host feature is installed. Find the registry key:

HKLM\SYSTEM\ControlSet001\Control\Power\ForceHibernateDisabled

Then, find the value GuardedHost, which will be set to 1 by default.

Change this value to 0 (the number zero) and reboot.

After reboot, hibernation will again be available.


	

FAQ: How can I track Windows 10 Azure AD Device Registrations?

This question came up twice for me this week, and the answer is not obvious if you’ve not gone looking for this info before.

You can actually track your Windows device registrations in two places:

One option is through searching your Azure AD Audit logs and filtering on Device Registration.

AAD_DeviceReg

Another is the Azure AD Power BI Dashboard, which received an updated in late June that includes a couple of new reports that include info on registered devices.
