Shell commands are incredibly useful when creating shortcuts or quickly accessing hard to get to locations. They can be used to pin shortcuts to the Taskbar or just to make your life easier.  For those that are preceded by “Shell:” when using them in shortcuts you need to add “explorer.exe” in front of them.  It should then look like this: explorer.exe shell:Personal
