Instead of downloading the same monolithic update package to every device, it downloads only the necessary set of files for the target system for which updates are available. The beauty of UUP lies in limiting the size of individual downloads. To quote Thad Martin, principal program manager at Microsoft: 'UUP is becoming the default and only way to download quality updates. The solution is absolutely modular in nature and it covers everything from monthly quality updates to annual feature updates to Windows Insider Preview builds.

Luckily, a community-led initiative provides the means to send manual queries to the Windows update framework, known as the Unified Update Platform (UUP), and construct a ready-to-use ISO image for every architecture and build out there. Furthermore, the company doesn't provide ISO files for every build released in the Windows Insider Program, hence performing a fresh installation for those builds isn't possible without being online and going through multiple hoops. To rub salt into the wound, Microsoft doesn't let you download official ISO files for Windows on Arm devices without a valid Volume License Service Center (VLSC) subscription. In case you need to service more than one PC, this design only exacerbates the problem. However, both the Media Creation Tool and the ISO files offered by Microsoft to regular users usually contain outdated builds, which means you have to download the latest monthly updates anyway during/after the installation phase.
