Reg key HKEY_CLASSES_ROOT\pngfile\shell missing OPEN sub key for many systems

Question

Hi,

I am trying to use the HKEY_CLASSES_ROOT\pngfile\shell\open to fetch the command to open PNG files, however I have see that many systems do not have the OPEN sub key and faile to open any application.

Could you tell me how can I get this entry for all systems? Is there a fix already available for this case? I am using all WIN10 systems for this.

Answer 1

The default application to open a specific file type normally set by the Open with context menu item. If you wish to do it by applying a registry hack then you could construct the key similarly to this one: HKEY_CLASSES_ROOT\textfile\shell\open\command

Hi Frederik,

Thanks for the reply, ideally yes the "Open With" and "Always use this option" should create the Shell -> Open -> Command, however it does not and we do not want every one to update/alter regedit and hence the question for a fix in a KBA or ...

assoc and ftype also does not lead to a definitive info on what is windows doing with it internally.
