File extensions did not show

My windows does not show the files extension even i uncheck the "hide extensions for knowns file type" in the file option menu.
Can anyone help?

 

Hi and welcome to the forum!

Generally or only for one file/couple of files?

 

Does This Happens With All File Types ?

Shortcuts Won't Show Extension Until "NeverShowExt" Policy Is Removed !

 

All the file type effected

 

Go To Start > Run > Copy And Paste Everything From The Code Box In Run Dialog And Hit Enter

Code:

cmd.exe /c ( reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "HideFileExt" & reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\HideFileExt" /s >>DH.txt) && start DH.txt

A Notepad Will Popup > Copy And Paste Everything Here !
