Microsoft introduces Unified Update Platform to reduce size of updates

Microsoft has revealed a new technology for rolling out updates that should make reduce the size of Windows updates. The Unified Update Platform (UUP) should make differential updates for all devices possible, for both mobile as computers.


A differential download package contains only the changes that have been made since the last time the device was updated, rather than a full build. Microsoft claims that the Unified Update Platform will reduce the size of large updates with 35%.

UUP should also make checking for updates much faster, Microsoft explains in a blog, “Using UUP, when your device checks for updates, the Windows Update service will evaluate which updates are needed by a given device. The Windows Update service then returns these updates to the device for download and install. Because more processing is being done by the service, this will lead to faster checks for update operations.”

UUP will first be used to release new builds to Windows Insiders. Microsoft plans to roll-out it out in stages. First to mobile devices of Windows Insiders, PCs of Windows Insiders should follow later this year.
