Windows 7: Restore All Windows

Let's say you have 2 Explorer windows you want to compare side-by-side. You switch to another program for a while. Now to switch back, you have to mouse over Explorer on the Task Bar, click on one window, and repeat for the second window. Is there a way to restore all windows from a certain program/group at once? Other people are asking the same question:

So far, there are only 2 ways, none very good:

1. Shift+right click > restore all windows
2. Ctrl+click several times

At this point, I'm willing to install additional software to change this behaviour.
