One of the big disappointments of the Pre-Beta build was the lack of the New Taskbar, which is referred to internally as the SuperBar. We had been told that the feature was not in the build at all. But Raphael, one of our friends from Within Windows, was handed a note at PDC instructing him to dig deeper into the bits to unlock the feature. He dismissed it, but luckily he stumbled on it anyways. It turns out, Microsoft protected the feature to the internal corporate network, but Explorer bypasses the check if it finds a cached result. Raph figured out how to cache the result, and whamo! SuperBar goodness for all. Hit this link for a semi-technical explanation, and the workaround.
