What’s new in the build 14959?

This build for Mobile has been published using the new update publishing system called Unified Update Platform (UUP). It’s the next generation of Microsoft’s delivery technologies to push the updates. One of the biggest community and customer benefits of UUP is the reduction you’ll see in download size on PCs. This has been already started rolling out to Mobile insiders in stages (starting with today’s build), and we expect to see it for PC Insider builds later this year and then IoT, HoloLens.

Microsoft added a new Zoom option in the View menu of Hyper-V Virtual Machines, where you can override the default scaling and set it to 100, 125, 150 or 200 – whichever matches your preference. Microsoft also fixed an issue where certain VMs wouldn’t display the remote desktop connection bar after entering full screen mode.
