With the leak of 9374, we expect to learn more about Microsoft"s plans for Windows 8.1 which will debut later this year, but before that happens, we have a walkthrough of the build that will show you some of the early changes to the platform.
Seeing that the last leak was 9369, this build is likely very similar to 9369 and may not show many new major features. But, even though the builds are relatively close together, there are a few new items for you to sink your teeth into and Winbeta.org has compiled a video for your viewing pleasure.
