Companies wishing to deploy SP1 in a controlled fashion will need to block it from downloading automatically, unless they already disable updates as part of company policy.
Earlier, Microsoft had suspended distribution of an update that is a pre-requisite for SP1 to be downloaded. Some users experienced difficulties while installing the Servicing Stack Update patch, but Microsoft said it has now issued a fix for the problem.
Microsoft chairman Bill Gates has also added fuel to speculation that the planned successor to Vista, Windows 7, may be brought forward from its expected release date in 2010.
While speaking at the Inter-American Development Bank in Florida, Gates is quoted as telling the audience that "sometime in the next year or so we will have a new version." Gates was referring to Windows 7, but it remains unclear whether he meant the complete version or a beta release will be available in 2009.
Microsoft said that Windows 7 is still "scoped to three years from Windows Vista's general availability", which suggests a release date in the first quarter of 2010. It added that it had no further information to disclose at this time.
