Product Affected: Deep Freeze Enterprise 8.51
Windows 10 Fall Creators Update 1709 (Build 16299) or higher

We've identified that the upgrade to the 1709 and up makes some changes to the boot control configuration on the machine and allows these messages to be displayed when restarting the machine.  We are working with Microsoft to resolve this issue completely.  To prevent this screen in the meantime, you can apply the following command to your machines: 

bcdedit /set {current} bootstatuspolicy ignoreallfailures

This can be deployed either through an elevated command prompt on a single machine, or deliver it via a batch script using the Deep Freeze Enterprise Console's "Push and Launch" feature to a group of machines.
