I blogged in 2014 about setting up client restore service on Server 2012 R2 Essentials. I wanted to do the same thing for Server 2016 with the Essentials role. I wasn’t surprised that I needed to use an updated Assessment and Deployment Kit (ADK). I was surprised when I discovered that the latest ADK, designed for Windows 10 version 1703, includes incorrectly-signed drivers, making it impossible to actually build images—or to use in Server 2016 with Essentials.
After choosing the minimal install as explained in previous article, the installed downloaded and installed 3.6GB of the ADK. I believe it was during the installation, this message appeared:
When I tried to Start the Client Restore Service installation in Essentials, it failed with this error:
I tried repairing the ADK installation, but that didn’t help.

This post has a workaround, which I didn’t use.

The fix does work: once the drivers have been replaced, the Client Restore Service was able to build the necessary images and start successfully;
