Windows 7 and Explorer Default Behavior
One of the things which immediately irritated me was the fact that if you use WindowsKey+E Explorer opens (and if you didn't know this, you just tried - right?) with My Computer as the default view, whereas the Taskbar icon by default opens up the Libraries location.
Credit for this goes to this page .
Also learned from this that pressing shift before right clicking on an icon on the taskbar reveals some extra options.
