Rafael on his blog posted a nice little tool to unlock some hidden features of windows 7:
Last week, I revealed a weird protection scheme around some unfinished features in Windows 7 (build 6801). I provided a buggy tool to enable the new Taskbar, then teased everyone with other features such as gestures, panning, and Desktop Slideshow. It wasn’t intentional, I just needed some time to rework the unlocking tool.
Rivera’s tool lets users access Windows 7’s new taskbar a feature that looks pretty similar to Mac as well as other unfinished bits of the operating system, including multi-touch gestures and a dynamic desktop slideshow that pulls images from Web-based feeds.
Understanding the risks involved in patching core system files, you candownload a copy of the tool, either off digiwebbs, or off his orginal post
