Microsoft announced a significant improvement coming to Windows Update. With Windows 10 Creators Update, update delivery will be faster once again due to reduced size of updates. Microsoft is working to use delta updates for consumer PCs once again.
The new update system was activated along with the release of Windows 10 build 14959, the latest preview build of Windows 10 Creators Update. It is called Unified Update Platform (UUP).
UUP will be available for every Windows 10 device including PCs, tablets and laptops, smartphones, IoT and Hololens devices. As of this writing, Microsoft is going to enable delta updates only for Windows 10 Mobile insiders. Later, it will be activated for the rest of Windows 10 Insiders.
Finally, UUP will reach the production branch with the RTM release of Windows 10 Creators Update, which is expected to be rolled out in March 2017.
Delta updates are relatively small packages which include only the differences between installed and new files. Microsoft noted that this will reduce the size of updates up to 35%. This will affect the update download and installation time, since smaller updates will be transferred and installed much faster.
The required delta value will be calculated by the improved Windows Update service. It will also allow upgrading the existing operating system to the most recent one smoothly and quickly. However, if the installed build of Windows 10 is very old, the update size can still be large because many changes would need to be delivered to the target OS.
Users with slow or limited Internet who install all updates consequentially will benefit from this change. This change in Windows Update will be welcomed by many users.
