Vista Service Pack 1, with 300 fixes, released to PC makers

Microsoft on Monday released Service Pack 1 (SP1) for its Windows Vista operating system (OS) to PC manufacturers, setting the stage for general distribution next month.

The update includes more than 300 fixes, including security patches for Internet Explorer, Outlook, Outlook Express and Windows Media player, as well as a number of data-protection features. The full list of fixes is available on Microsoft's TechNet site.

The Redmond, Wash.-based computing titan has also created Vista SP1 DVDs for distribution to enterprise subscribers to the company's volume licensing program.

Microsoft disclosed last summer that Windows XP Service Pack 3 will also be released during the first quarter of this year.

Analyst firm Gartner last year advised companies planning to deploy Vista not to wait for the release of SP1.

“SP1 will include all previously released updates for Windows Vista. It also will include security, reliability and performance improvements," he said.
