Where is the open command of images in the registry in Windows 10

Question

Usually, the program that opens a file type is stored in the following key in the registry (where filetypename is the name of the file type):

HKEY_CLASSES_ROOT\filetypename\shell\Open\command

But for image files such as PNG or JPG, the only key in the shell key is printto, which is the Print command. However, when I right click on the image, there is still an Open command, but it doesn't seem to be anywhere in the registry. Why is this? Can files have commands that aren't in the registry? Or is this command's key somewhere else in the registry?

Answer 1

I know this because I just did it for "Edit with VbsEdit", a custom change for the .vbs filetype. This worked on a Windows 7 machine, after I created each key from ".vbs" down to "Command":

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SystemFileAssociations\.vbs\Shell\Edit with VbsEdit\Command]="C:\Program Files (x86)\Vbsedit\Vbsedit.exe" "%1"

Obviously, for your question use:

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SystemFileAssociations\filetypename\shell\Open\Command]="C:\Path\OpenProgram.exe"

... and "C:\Path\OpenProgram.exe" is the full pathname to the desired default opener.
