Microsoft releases Windows 10 build 14959 for PC and Mobile devices enrolled in the Fast ring as part of another test for the Creators Update, which as you know will release in early 2017. Presumably sometime in March of next year.
Windows 10 build 14959, according to the software giant, doesn’t include any significant visual changes, but it introduces a new update publishing system known as Unified Update Platform (UUP).
In addition, this update for the Windows 10 Creators Update improves display scaling on virtual machines using Hyper-V, and there is a slew of fixe for PC and Mobile devices.
Here are more details about the new improvements and fixes for build 14959.
Unified Update Platform
Microsoft calls it “Unified Update Platform” (UUP for short), and it’s a new update publishing system that will help to optimize the delivery of new feature updates.
Through this new technology the software giant is expecting to deduce every major feature update by 35 percent. This is possible because the new download package will only contain the changes made since the last update, instead of having to download and reinstall the operating system entirely.
Starting with build 14959, the Unified Update Platform is available for Mobile devices, but it’ll also work across PC, tablet, IoT, and HoloLens.
In addition, Microsoft is also redesigning the way devices check for updates and making the experience more efficient. In the Windows 10 Creators Update, when a device checks for updates a lot of the processing will be handled by the Windows Update service, which will translate in a faster update experience, fewer resources, and reduction of power consumption that will benefit everyone, especially mobile devices.
