According to a post on the Windows Vista official blog, Microsoft decided to stop a software update for Windows Vista, which has the role to facilitate the automatic installation of the upcoming Windows Vista Service Pack 1.

Soon after the update, called KB937287, was released several users started complaining about the problems they encountered after installing the software. According to the reports posted on various forums, some users have experienced an “infinite” loop of restarts, while others said their system crashed and went unresponsive after installing the update.

Although, Microsoft said only a small number of clients were affected by this issue, the company decided to temporarily stop the distribution of the update.

“We are working to identify possible solutions and will make the update available again shortly after we address the issue. Customers who may be experiencing this issue can use system restore to correct it or contact 1-866-PC-Safety for help troubleshooting,” wrote Nick White.

Microsoft announced earlier this month that its Windows Service Pack 1 reached the RTM status, but the update will be officially released in mid-March, first in five languages.

According to TechArp, the End-User Manual Update will be available on March 18, while the Automatic Update is scheduled to be released on April 18.

In the meantime, Microsoft unveiled a new version of its Windows XP Service Pack 3, which is one stop closer to the final release.
