Windows Server 2016 has a lot of things disabled out of the box as to improve responsiveness and reliability. One of those things is Windows Photo Viewer. In this quick tutorial, I'll show you how to enable it. Now as you read through this, you might be wondering if there is a way to enable the Photo Viewer with Windows add / remove features or some built-in utility like that, but as much as I searched, I could not find a way to do it from within Windows Server 2016. So this method uses a donor OS.
