Only days after the release of build 5456 of Windows Vista, Microsoft already plans to release another interim build, no later than this week.
The build supposedly consumes fewer system resources and the long-awaited new Aero Basic theme.
The build number is currently unknown and the build will likely be released to usual technical beta testers as well as TechNet subscribers.
"Vista in its beta form is pretty taxing on the system. It's slow and a little non-responsive," said Mike Sievert, corporate vice president of Windows client marketing at Microsoft.
"That piece of software is now about nine weeks old and that may not sound like a lot but at this stage, that's an old version in software terms."
"You'll see a huge difference [in performance]," Sievert said of the interim release, noting Microsoft is recommending 512 Megabytes of memory when testing the new code.
