This is already a fairly old article, but I'm pretty confident it never made OSNews' front page. In this article, the author proves that Windows XP can be installed, and 'run', on processors with as little as 8MHz. "The target of this project was to find the weakest system where you can run Windows XP. Keep in mind, that Microsoft official requirements are a CPU with 233 MHz an 64 MB of RAM. But that had to be beaten!"
