Windows Shortcut: Minimize All Windows [UPDATE]

A while back, I posted a note about a Windows keyboard shortcut for minimizing all currently open windows.

It turns out that there is a better way:

<Windows>-M -- to minimize all windows <Windows><Shift>-M -- to undo the minimize all

That is, press the <Windows> key and the <M> key together to minimize, and press the <Windows,> <Shift>, and <M> keys together to undo. (The <Windows> key is, of course, that key with the Windows logo on it, between the <ALT> and <CTRL> keys, on Windows-style keyboards.)
