Future Windows 10 updates will be slightly easier on those with data quotas. Microsoft has announced a new update to the Unified Update Platform that only downloads files that have changed since the last update.
At the moment, major Windows 10 updates involve re-installing the operating system; essentially starting over from scratch. This is more of a concern to those on the Windows Insider programme, and matters less to users of the retail version of Windows 10.
According to Microsoft, the differential download size for its latest Insider update was only 910MB; compared to the canonical size of 2.56GB. It represents a massive improvement in download size; which will likely come as a welcome news for those growing tired of massive Windows updates.
Regular Windows 10 users are unlikely to see this kind of improvements. The differential download only applies to major updates; which happens twice a year at most. The files are different enough that Microsoft is only expecting a 35 percent decrese in size.
The UUP is being rolled out to consumers with the Creators Update coming this spring. Although that means that the benefits of the system will only be seen with the next update; which is supposed to be scheduled for some time later this year.
