The customer feedback is being solicited through the Technology Adoption Program (TAP), which regularly solicits feedback from Microsoft (Quote) customers and beta testers.
"We are currently gathering feedback about Windows Vista that will influence what goes into SP1. It is important to note that any critical fixes needed for Windows Vista will be delivered via Windows Update, prior to Windows Vista SP1," Microsoft said in a statement to internetnews.com.
Microsoft added: "It is too early to provide any firm date range for SP1's delivery. In general, we expect the first service pack for Windows Vista to be released in a time frame similar to that of service packs for previous versions of Windows."
Thurrott has been working with Vista since the final code was finished in November, and reports that it's quite solid. So he can't see Vista needing a service pack to fix bugs in so short a period of time following the Vista release.
But at some point in the past, Microsoft wanted to release Longhorn, the codename under which Vista and the forthcoming server were developed, at the same time. However, as the release plans slipped, Longhorn server was put on the back burner and the two products fell out of sync.
As Thurrott pointed out, a kernel upgrade would be needed to provide support for the many new networking and security features being added to Longhorn server, such as Active Directory updates, policy-based networking, the "componentized" operating system and a significant upgrade to Terminal Services.
Gartner analyst Michael Silver also said he expects a service pack to coincide with Longhorn server. He's just not sure when it will ship. "It makes perfect sense they would ship a service pack when they ship Longhorn server to bring it up to date. The question is when is Longhorn server going to show up?"
