Thats O'Reilly... the popular publisher of books on Programming Languages and Operating Systems... not Bill O'Reilly the host of the Fox News show "The No Spin Zone" which my mother is hooked on like a heroin addict.

WindowsDevCenter.com is devoted to the operating system that I thought O'Reilly didn't like to talk about... most of their books have concentrated on Linux, and languages that run on those platforms... but I have seen a wider variety of books on .NET and Windows from them... and so it's only natural that they should have a website devoted to it as well.

If you've ever programmed on Linux platforms, then you've definitely read the books published by O'Reilly like I have. They are always excellent resources, and I'm glad that they're finally coming to the dark side. :D There are a wide variety of articles on Windows programming, as well as tips and tricks to improving your Windows experience.
