"We believe we can get below 1% idle CPU utilisation with Windows 7." What technical tricks is Microsoft using to try and get the next release of Windows to those levels?
Early reviews of the Windows 7 M3 release have generally agreed on one point: the speed is surprisingly good. It turns out Windows 7 runs quite healthily, especially given that it is still a pre-beta release and that it's largely based on Vista, which doesn't have much of a reputation for efficiency.
Some of that improved performance is probably due to what's missing. The M3 code is API-complete but doesn't include many of the user interface elements that will appear in the final release. M3 doesn't do any serious checking on whether the product is official or not (a situation which has led to extensive torrent exchanges of the code), something that's bound to be addressed with some cycle-hogging Windows Genuine Advantage tweaking before the official commercial release.
