PC World offers up some info about Windows 7, which is always of interest:
The core code for Microsoft Corp.'s Windows OS is undergoing a rewrite to make it slimmer for use in a wide range of future products, including Windows 7, the OS that will succeed Vista.
The internal project, code-named "MinWin," is not being readied for a product just yet but will be part of Windows 7, said Eric Traut, a distinguished engineer, during a recent presentation at the University of Illinois. A video of his talk has been posted online.
"A lot of people think of Windows as this large, bloated operating system, and that's maybe a fair characterization, I have to admit," Traut said. "But at its core, the kernel, and the components that make up the very core of the operating system, is actually pretty streamlined."
Traut showed a demonstration of MinWin, which lacks a graphical user interface. It takes up just 25M bytes when stored on disk, compared to the massive 4G bytes the full Windows Vista OS needs, Traut said.
MinWin can run on under 40 M bytes of RAM, he said. "That's kind of proof there is actually a pretty nice little core inside of Windows," Traut said.
But Microsoft still wants to shrink it. "It's still bigger than I'd like it to be," Traut said.
Microsoft has said it will release Windows 7 by 2010, although the company has not revealed much detail on its features.
There's just one problem with all this. MinWin isn't new. In fact, I wrote about it years ago here, here, and here. It's part of Windows Vista and 2008, and is at the core of these OS's internal componentization.
