I'm talking about the HKEY_CLASSES_ROOT registry keys for Windows 10. Changes to the keys in background
changes the right click menu when you've clicked inside of a folder. But what do changes to the keys in shell
do?
(To be clear, I'm talking about the shell directory that is an immediate child of the Directory key, on the same level as the Background key. Of course, both this shell key and the Background key have a subkey also named shell.)
