I recently discovered process explorer (https://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) and would like to add it to the context menu when you right click on the taskbar. It has the option to replace the task manager but I want to keep both. I want to add a menu called Process Explorer underneath of task manager, where the red arrow is pointing. Where can I find this in the registry? I've been searching but I cant find where this context menu is under the registry editor.
EDIT: I am on Windows 8.1 pro, and know how to use Registry editor and know a little on resource hacker. I have been looking for any register values with Taskbar, task manger, lock the taskbar etc. but I have found nothing. I made a copy of the explorer.exe to dissect but I don't see anything really editable. Any help is appreciated :)
EDIT2:I know how to add custom items to the right click context menu, but I need to add it to the context menu on the taskbar, which I cannot find. Can someone Please help me!!!
