I just got the news that Windows Vista Service Pack 1 is available for public download. It’s not the final version but it’s at least the first release candidate and it should be extremely close to the real thing. It’s a big download – 32-bit version is between 440 and 550 MB, and the 64-bit version is between 730 and 880 MB – and you might need to uninstall it completely when the Vista SP1 Final is ready. If you download it and try it out, please drop a comment.
