A "show desktop" shortcut that actually minimises all windows?

While I know that the "show desktop" button that is by default on the far right of the taskbar does the job pretty well, it unfortunately does not play nicely with multiple monitor programs/rainmeter.

So I was wondering if it was possible to write a shortcut that does the same thing as manually minimising every window. (The difference being when you manually minimise all windows is that when you re-maximise a window, only that specific window opens. Upon re-maximising a window after clicking the "show desktop" button, EVERY window re-opens.)

I would be nice if I could minimise each desktop/monitor separately, but I'd be happy just with a feature to minimise all windows.

Any ideas?

Unfortunately that just does exactly the same as pressing the show desktop button. >_<

I'm pretty sure you will find a solution using AutoHotKey (AutoHotkey) - a script may already exist or you will be able to easily write one yourself.
