Specifically, the build makes setting up and controlling a user account on the OS "less chatty," said Mike Burk, a Microsoft product manager for Windows Client. "Testers said there were too many prompts and dialogs, so we reduced the number of those," he said.
The build also improves the Windows Media Center feature in the OS so it more quickly shuts down and starts up, Burk said.
In conjunction with the build, Microsoft also released an updated SDK (software development kit) so developers and software vendors can develop applications on top of the new release, he added.
Overall, build 5472 of Vista shows some of the final tweaking Microsoft is making for performance and quality as it prepares to finish Release Candidate 1 of Vista, which is due out by Aug. 31, Burk said. Microsoft is still targeting a final release of Windows Vista for business customers in November, with general availability of the OS on PCs in January 2007.
However, Burk echoed comments expressed by top Microsoft executives that those release dates are only targets, and the "actual and final dates will be based on quality of the product." That kind of talk that has led many to believe the release of Windows Vista will be delayed even further.
To add fuel to that belief, Microsoft recently announced that business customers will have to wait until the end of the year for Office 2007, which has been on a similar release track to Vista and was scheduled to reach business customers in October. The company also pushed the consumer release of Office 2007 a few months beyond its scheduled January 2007 release.
