Windows Explorer may be getting more complicated in Windows 8, but if you prefer a minimalist look, you can actually slim down Windows 7′s Explorer with a simple tool. The Command Bar Tweaker lets you either remove the command bar entirely or auto-hide it, so you can still access it if you mouse over it. Make sure if you use the auto-hide feature that you’re using the default Windows Aero theme, not Windows Basic or a third-party theme.
Windows 7 Command Bar Tweaker is a free download for Windows 7 only.

I like the idea of the auto hide option, especially for my family's netbooks.
Awesome, now all I need is something to remove the glass borders to the window.
