Heh, I installed ImageGlass when Windows 10 somehow broke their image preview utility, and I don't think I've ever updated it since (or received any notification to update).
If I remember correctly, I still think Windows Photo Viewer was much better than ImageGlass. All I want to do is quickly browse through a couple of photos in a folder.
The underlying code is still there. You just have to reenable it with a registry tweak. https://www.tenforums.com/tutorials/14312-restore-windows-ph...
