Back in October, Microsoft had announced the public preview of on-premises UUP (Unified Update Platform) which promises faster and smaller Windows update downloads. Fast forward four months to today, the company says the feature is now almost ready to ship, as the first UUP on premises updates are set to hit on March 28th.

In the update workflow diagram below, Microsoft has explained how UUP can lead to smaller update download sizes for client PCs after the initial one-time 10GB increase in the case of distribution points for the Windows 11 22H2 feature update.

With the help of UUP, Microsoft is promising up to 30% smaller and hence faster downloads. Other improvements include cumulative and feature update integrations which means less reboot time, reduced client downloads, and more. In a Tech Community blog post, Thad Martin, a Principal Program Manager at Microsoft, has explained the benefits of UUP outlining all the improvements expected from it:

That extra 10GB foundation on distribution points enables the awesome new capabilities that come with UUP. The same fundamental improvements we've been making over several releases are now available to enterprises with UUP on-premises update management. In short, you'll experience faster and smaller quality and feature updates, reduced disk space and usage, and fewer reboots:
  • Up to 30% smaller client downloads for quality updates
  • Cumulative update integration with feature updates (i.e., get current in one reboot)
  • Seamless retention of installed language packs and optional features (FOD) during feature updates
  • Reduced client downloads for feature updates (i.e., inbox app downloads are conditional)Automatic OS healing during the update process
  • End-user acquisition of language packs and FOD

It is for enterprise-only. It is not for Windows Update on unmanaged (home user) systems. The enterprise installs UUP on their own hardware per the requirements.

Back in October of 2022, Microsoft had announced the public preview of on-premises UUP (Unified Update Platform) which promised faster and smaller Windows updates. About a month and a half before the rollout, the company shared more details about UUP claiming up to 30% faster and smaller downloads. Microsoft also added that .NET update performance will also be significantly better on Windows 11 22H2 due to as .NET Framework updates would now be a part of UUP as well. Of course, it wasn't bug-free as there was a WSUS upgrade issue caused by the accidental removal of necessary UUP MIME types.

UUP Media Creator, a set of third-party tools for scanning and fetching updates from the Microsoft Unified Update Platform (also known as UUP), received a small update to resolve issues with downloading files for the recently released Windows 11 Moment 4 update. Version 3.1.9.0 is now available for download from the project's GitHub repository.

Gustave Monce, the creator of UUP Media Creator, announced the update on its DuoWOA Announcements Telegram channel:
A new version of UUP Media Creator just got released to address important issues that prevented both downloading all files, and creating setup media for Windows 11 Version 23H2 (Moment 4) release.

If you had errors when making media for this, please relaunch the uupdownload command, this will download some missing files, and won't redownload what you already have, and then relaunch the conversion command using the new version.
And here is the changelog published on GitHub:
