How to hide known file extensions in Windows

Hiding file extensions in Windows

By default, the file extensions of known file types that are associated with some software installed in your computer are hidden. Sometimes, some software or even the user makes them manually all visible as you can see on the screenshot below, where the TXT file extension is visible in Windows Explorer, because the TXT file type is associated with a Notepad program.
