Microsoft is today rolling out Windows 11 build 22000.100 to Insiders running Dev channel builds. The cumulative update brings with it - among other things - further integration of Teams and some additional visual tweaks to the taskbar.

What these builds are yet to add, however, is the ability to run Android apps, something that the firm announced during the Windows 11 unveil event. When the capability does make it to the OS, users will be able to run Android apps from the Amazon Store that will be housed within the Microsoft Store. Currently, there is no word on when that feature is expected to be added.

With that out of the way, here is the complete list of features being added with build 22000.100:

Changes and Improvements

• We have started rolling out Chat from Microsoft Teams to Insiders in the Dev Channel. Not everyone will see it right away,
• The hidden icons flyout on the lower right of the Taskbar has been updated to match the new visuals of Windows 11. (Please note – it may not look right after updating to this build – toggling between two themes will correct the issue.)
• 

   

• We added the ability to quickly access Focus assist settings directly from Notification Center.
• 
  
•  
• When a background activity from an app requires attention, the app will flash on the Taskbar to get your attention. In Windows 11, we have updated this design so that it still grabs your attention but with a calming treatment that minimizes the impact of unwarranted distractions. The subtle flashing eventually stops, and you will see a slightly red backplate and red pill under the app icon continuing to note a background activity needs your attention. Let us know what you think!
• 
  
•  
• The touch keyboard icon in the Taskbar has been adjusted to be more consistent with the size of the other icons in the corner of the Taskbar.
• The Taskbar calendar flyout will now fully collapse down when clicking the chevron in the top corner to give you more room for notifications.
• In the latest Microsoft Store update rolling out to Insiders, we made navigation in our new Microsoft Store feel fast and fun. When you select an app or movie you’re interested in, you might notice some animations that help you keep track of what you’re browsing. Give it a try, we hope you like it as much as we do.

As usual the company has also been hard at work fixing issues with Windows 11 that have been reported by Insiders, among other things.

With the fixes come the list of known issues that users must be aware of. With the OS is still being prepped for the Beta and Release Preview channels, there are a bunch of hiccups that might make the OS unstable for daily use. You can check out the list of known issues here.

Windows 11 build 22000.100 is rolling out via Windows Update to Dev channel users running the latest version of the OS. As mentioned earlier, there is no word yet on when these builds will begin rolling out to the Beta channel, but it should happen soon as the firm skipped releasing the latest 21H1 updates, citing the impending release of Windows 11 builds. Currently, there aren't any official ISOs available either for those hoping to perform a clean install of these builds.
