There are number of utilities available that mimic the functionality of Apple Expose, but my favorite that I’ve tried so far is Switcher.
Switcher 2.0 – www.insentient.net (DEAD)
Though Switcher has been out for a while, version 2.0 was just released a couple months ago. It adds a number of cool features and is even available in both an executable and a non-installer format.

Once Switcher is running, call it into action by pressing Win (left) + Tab. If you don’t like that key combo, you can easily create your own.
By default, Switcher is set to Tile view:

If you have Expose envy on your Windows machine, Switcher is best free tool that I’ve found. Plus, I love that it does not even require installation.
