In another blow to Vista the SP2 will be out later than expected.

Microsoft has annonced it will delay the release of Windows Vista Service Pack 2 (SP2) by at least a month, and the company will now ship it to manufacturing sometime in May or June.  SP2 was originally intended to be released this February, with the Release to Manufacturing (SP2 RTM) scheduled for April.

The first beta of SP2 was made available in December of last year. Right now, Microsoft is undoubtedly rushing to get Vista SP2 out well ahead of the release of Windows 7, its next major operating system.
