As we blogged last week, The Vista SP1 Release Candidate is now available for public download. If you’re looking to see what fixes are contained in the Service Pack, check out this post by Long Zheng of istartedsomething. Keep in mind, this isn’t the final release, it is a release candidate, so if you’re going to go all install happy, take the necessary pre-cautions. (Ask Matt about that if you’re interested.
Here’s the download link and more info on the release. Note that the SP1 RC is also listed as being available on Windows Update. So, if you want to hold off you might want to check your Windows Update settings and adjust accordingly.
