Same as before, this exposure update log is still Russia's breaking news WZor. As you can see from this log, Win10 development in the final stage has no built-in software updates, and the main work is focused on bug fixes.

However, from the development progress of Microsoft, the Build 10164 version is more comprehensive, and is currently undergoing the test of the first link Canary ring.
