Management, revealed that, due to integration issues with third party hardware drivers, the service pack will be served through Microsoft Update, Windows Update and the Download Center starting with mid-March, and via Automatic Updates in mid-April.

In addition, Microsoft also had to serve two remaining Vista SP1 updates out of the total of three prerequisites for the service pack. It did so with the latest monthly patch cycle on February 12, 2008. Having dropped KB935509 in January, only KB938371 and KB937287 remained. But Microsoft hit a speed bump with the update for the Vista installation software feature, namely KB937287. End users reported that the operating systems on which KB937287 was delivered via Automatic Updates remained frozen in the "configuring updates stage 3 out of 3 %" stage, and then entered an infinite loop of reboots. Microsoft has finally reacted to user complaints and stopped the distribution of the update in question.

"We (Microsoft) have heard a few reports about problems that customers may be experiencing as a result of KB937287, the servicing stack update, and I wanted to provide a quick update for you. Immediately after receiving reports of this error, we (Microsoft) made the decision to temporarily suspend automatic distribution of the update to avoid further impact while we investigate possible causes. So far, we (Microsoft) have been able to determine that this problem only affects a small numer of customers in unique circumstances. We (Microsoft) are working to identify possible solutios and will make the update available again shortly after we address the issue" state Nick White , Windows Vista Product Manager.
