For those rabid, open-source conspiracy theorists still holding on to the popular notion that Microsoft is secretly working on its own version of the Linux operating system, Bill Hilf has some sobering news. "The bottom line is, we"re wholly, 100 percent committed to Windows and think we can do amazingly powerful things in the operating system," says Hilf, director of platform technology strategy at the Redmond, Washington-based software giant. "There"s a ton of stuff we can do to innovate. We don"t see that level of innovation [in Linux] that makes us say there"s [anything] out there that"s better than or more effective than what we can do."
