First, I tried to load the 7000, 6801, 6608, 6469, and 6002 visual styles under Windows 7 7601. 7000 loaded perfectly, so I will skip it.
You can see how they slowly break as I go down in versions. This is mostly due to the Superbar and newer start menu graphics 7 introduced. But what if we tried it under beta versions themselves? (first image is from Splitwirez)
These also work on other builds of 7, and Vista RTM. Feel free to experiment if you want to find some more cursed goodness.
