Custom profile: hide known file extensions

Mykey You can do this via a simple Powershell Script or a Remediation Task via Intune.

Something like this:

try
     {
         Set-ItemProperty -Path HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced -Name HideFileExt -Value 0 -ErrorAction Stop
     }
     catch
     {
         Write-Error -Message "Could not write regsitry value" -Category OperationStopped
         $exitCode = 1
     }
