A private tester group have got their hands on a beta of Microsoft's Windows Vista Service Pack 1, ahead of the anticipated launch early next year.
In late August, Microsoft for the first time offered a release schedule for SP1. At the time, the software giant said the beta would become available this month to between 10,000 and 15,000 testers.
One beta tester, Brandon LeBlanc, author of the Windows Experience blog, has already written about his experience with SP1.
In addition to a couple of minor user interface changes, he has noticed improvements to the overall responsiveness of his PC and laptop. He particularly noticed that resuming activity after the machines hibernate, and copying files from one directory to another, work faster.
LeBlanc also reported improved battery life on his laptop.
SP1 also appears to have solved some wireless networking issues he had, which caused his computer to lose connectivity often, especially after the laptop was hibernating. Since he installed SP1, that problem has gone away, he said.
Microsoft had promised that SP1 would include a speedier resume function following hibernation. It also said the update would include improved performance of Internet Explorer 7, particularly for websites running AJAX.
Microsoft will distribute SP1 via Windows Update, its automatic update service. Alternatively, corporate administrators can use a standalone version of SP1 in conjunction with other programs they may use to distribute software to computers.
Microsoft has also released Release Candidate 0 of Windows Server 2008, code-named Longhorn. That means customers can download and try out the latest version of Windows Server 2008, including for the first time a preview of Viridian, Microsoft’s virtualisation technology. The release of the RC0 means that development and testing are progressing and that the server code is entering the final stages of testing, Microsoft said.
Last month, Microsoft pushed back its forecast for the release of Windows Server 2008 from this year to the first quarter of next year.
