Getting back the old Alt-Tab windows switching behavior in Windows 7

Problem

When you run more than six applications on Windows 7 and you press Alt + Tab, icons representing the first six applications and the desktop appear on the first row of the grid and you can cycle with Alt + Tab + Tab... through the six most-recently used windows the usual way, but the seventh and other less recently used windows don't follow the same rules. Instead they get grouped together according to their application, but disregarding whether they were recently used or not. This new behavior is mentioned here. I am very used to the old way of cycling and the new system is driving me crazy. I tend to have 20 or so windows open at one time and I frequently need to alt-tab to the seventh or eighth window on the stack, but it doesn't work the same any more. How do I put back the old behavior, so that Alt + Tab + Tab + Tab ... goes through the whole list in most-recent to least-recent order?
