14 DAY TRIAL // Since Windows 8.1 is alive and kicking, Microsoft has started shipping the first round of updates to computers that are already running it, thus trying to deliver the latest fixes as soon as possible.
KB2883200, KB2884846, and KB2895219 are all distributed via Windows Update, so make sure you connect to the Internet and check for more patches in case you’ve already deployed Windows 8.1.
Microsoft doesn’t say too many things about these updates, as it only mentions that they’re supposed to correct issues found in the Windows OS.
Most likely part of the GA Rollup cycle, these updates should be installed as soon as possible, as they are very likely to implement new options and address performance glitches found in the stable version of the operating system between RTM and GA.
