After almost a month hiatus, Microsoft makes available another preview release for Windows 10 Creators Update Version 1703. The new Windows 10 Insider Preview build for Windows 10 Creators Update milestone is build 14986, or more specifically 14986.1000.

Windows 10 Build 14986 is released to Windows Insiders on the Fast ring on December 7th, 2016, and those on the Slow ring a week later on December 14th, 2016. The ISO images for Windows 10 Build 14986 are not released together with the flight to Slow ring, but ISO images do come another week later, on December 21st, 2016.

Windows 10 Build 14986 is the first publicly available build of Windows 10 that fully embraces the Unified Update Platform (UUP), which simplifies the update process for Windows 10. UUP enables differential downloads for all devices built on the Mobile and PC OS so that Windows only downloads package contains only the changes that have been made since the last time you updated your device, rather than a full build, effectively reducing the download size. In addition, with UUP, the cloud Windows Update services will evaluate which updates are needed by a given device instead of letting device processing it. Like the Universal Windows Platform (UWP), UUP functions across Windows 10 PC, Mobile, IoT, and HoloLens.

The new features, enhancements and improvements in Windows 10 Build 14986 mainly involves Cortana, Game Bar, Windows Ink, Narrator and input method (IME) for Asian users, where details could be found on Microsoft.
