Show extensions for known file types in Windows Server 2016

In several versions of Windows and Windows Server, Microsoft has chosen to hide extensions for known file types such as .doc, xls, .mp3, .txt, etc. For ordinary users, the extension of a file does not say anything to them as it does not they are able to recognize the difference between them. Personally, I prefer to know the extension of a file, known or unknown, visually when I see it in File Explorer.

In today’s article, you’ll see how to enable the display of extensions for known file types, both within the Windows and Windows Server GUI, as well as through Group Policy settings so that you can then apply to your users.
