From what I see, "HideFileExt" is a Value, not a Key and should be under the "Advanced" key. If so, you can delete this value by just adding the following command to a batch file (.bat) that executes as startup script reg delete HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v HideFileExt /fHTH, JWInfo on the 'reg' command can be found here: http://technet.microsoft.com/en-us/library/bb490984.aspx
