Microsoft has released another Windows 10 "19H1" build, as the company has started to work on the next major feature update for its operating system. It comes with the same changes as the latest build for Windows 10 Redstone 5 (also known as Windows 10 October 2018 Update).

Windows 10 Build 18214 is rolling out to the Windows Insiders in the Skip Ahead ring and it comes with one important change. That is the Your Phone app. Microsoft has finally added support for Your Phone app in Windows 10 19H1 builds after previously testing it with Fast Ring Redston 5 Insiders.
