Microsoft is expected to release a new build of the technical preview for Windows 10 in the very near future, according to their own words and now we know a little bit more about what to expect. The only build so far to be released to the public is 9841 but the next iteration will likely be in the 986x class of releases but of course, anything could change with Microsoft's internal plans before release.
Another update to the OS in the build, besides the addition of transitions, is the behavior of the Network function in the charms bar. In the current build, 9841, it acts much like Windows 8.1 where all the action happens inside of the Charms bar. In later builds of Windows 10, this functionality has changed and when you click the network button on the Charms bar, it opens up the settings in a new window.
In the new Windows you get more access to Wi-Fi settings and the typical list of available hotspots. Also, VPN controls can be accessed from this view too.
It's actually a rather large change to the workflow of the Charms bar but considering we know this feature will be heavily modified before launch and will likely go away for desktop users, this is more than likely a stepping stone on that path. What we mean is that when you see how the later builds operate, don't get too caught up in the functionality as it will likely change before launch.
More so, this update may not make it in to the public release of the technical preview but know that it is currently functioning this way on internal builds.
