2.99 GB for ESD on 64-bit Build 15031 for example). Recently, I've compared Insider Preview major builds between the older ESD versions and the UUP versions and have seen differences of 11 to 12 percent (2.58 GB for UUP vs.

Microsoft is making progress but still has some ways to go to hit that target.

Microsoft says its goal in using UUP is to reduce downloads by somewhere around 35 percent between a typical Windows 10 client and the corresponding electronic software download (ESD) or cabinet (CAB) file equivalents for the same update(s) downloaded the old-fashioned way. Next, instead of downloading the same, single, large and monolithic download file to everybody, it downloads only those files for the target system for which updates are available. This means that Windows Update scans your PC's component store and packages up only those update files that need to be applied to your system before it does any downloads. The afore-linked blog post describes the files that get transferred via UUP as 'a differential download package' instead of a 'full build.' Thus, UUP is best understood as a technique designed to limit download size, since smaller downloads match those user desiderata quite nicely. The impetus for this came from user feedback about how Windows Update would benefit from reducing consumption of local processing resources to improve battery life, and for download sizes to be smaller to complete more quickly and consume less bandwidth. In the name for this new update, вЂUnifiedвЂ™ refers to the ability to service all potential Windows devices - PCs, tablets, smartphones, IoT devices and Hololens - from a single update platform. What is UUP, and why is Microsoft using it for updates? The original post is well worth a read, if you're into the nitty-gritty details. This is explained in some detail in a Windows Insider blog post entitled ' Introducing Unified Update Platform (UUP)' that posted on November 3, 2016, so I'll just hit some high points here. It changes how Windows Update works in a profound and interesting way. The Unified Update Platform (UUP) was introduced to the Windows 10 Insider Preview with Build 14986 on December 11, 2016.
