Vista SP1 auto updates also halted

Microsoft confirmed Tuesday that it has stopped automatic updates of Vista to Service Pack 1 in the wake of a newly discovered glitch.

The problem, which has also halted the availability of Windows XP Service Pack 3, prevents Microsoft Dynamics Retail Management System from working with either operating system update.

"We are temporarily holding any additional automatic distribution of Windows Vista SP1," Microsoft said in response to an inquiry from CNET News.com. The company said it will continue to make Vista SP1 available for manual download. Microsoft had just started pushing out the Vista service pack last week via automatic updates.

"While we are recommending that customers running Microsoft Dynamics RMS should not install SP1, there are many other customers who can benefit from installing Windows Vista SP1 immediately, so we are maintaining availability via (Windows Update)," Microsoft said. "We are delaying the release of Windows XP SP3 and holding any additional automatic distribution of Windows Vista SP1 as a precaution and to help ensure that our customers have a great experience with Windows."

The company has not yet described the problem, beyond saying it is a "compatibility issue." I have also asked for data on how the problem was discovered, why it took until XP SP3 to find it, and how many users run Dynamics RMS.
