Microsoft released preliminary update KB4529943 for Windows 10, version 1903
A little later, the update will be available to Windows 10 devices that are not involved in the UUP Insider Program.
In November 2016, Microsoft shared its plans to migrate from a standard update deployment system in Windows 10 to a Unified update platform. The main advantages of UUP are reducing the size of updates and reducing the time it takes to deliver and deploy updates for Windows 10.
Microsoft claims that the new method can reduce the size of updates by about 35%. UUP uses differential update packages – devices receive only the changed code, and not all packages again.
Differential boot packages contain only changes that have been implemented since the previous device update, and not a complete assembly. After implementing UUP, when switching from one major update to another, users will notice a decrease in the size of downloaded files by about 35 percent.
KB4529943 – update for the Unified update platform for Windows 10, version 1903. On November 7, the update became available to users participating in the UUP testing program. Microsoft emphasizes that the update should only be installed on the devices of participants in the testing program. The update is also available for manual installation from the Microsoft Update Catalog.
This update is available to a limited group of users who participate in the Unified Update Platform (UUP) Insider Program. KB4529943 is in a test phase and can only be installed on devices connected to the UUP test program.
Microsoft is about to update the knowledge base article when the update is available to all users.
Similar updates are available for other versions of Windows 10:
KB4514987 for Windows 10, Version 1809
KB4512745 for Windows 10, Version 1803
Reducing the size of updates should be a useful improvement for most users and organizations that use Windows 10. Updates will be delivered faster, and many users will notice accelerated installation.
