I have been trying to find some reference to this for a couple days now, and the only thing I can find is how to add menu items to your form's context menu.
I am wanting to manipulate all windows' context menus to include a custom menu item.
Conceptually, I think I'm going to have to loop through and grab the handles of all processes and intercept their context menus and override the WndProc() method per process, but I'm struggling to find information to point me in the right direction.
