The roll-out for the Windows 10 Fall Creators Update began around a week ago; the feature update includes interesting new features like OneDrive Files On-Demand, an anti-cheat system and parts of the Fluent Design System. Today, Microsoft has detailed why this update is being rolled out gradually, as opposed to a quicker and wider release.
Initially, only devices which the company has tested itself or via Insiders receive major feature updates like this, as that helps in getting focused feedback, particularly with regards to application compatibility. Primary users of these devices, including those who are part of the Insider programs, then assess the update, and their opinions are then evaluated to identify and remove any number of newfound bugs.
Microsoft has also reiterated the latest security capabilities provided by this update, mentioning that it is currently "the most secure version of Windows 10." Furthermore, the company claims that the download size for feature updates has now been reduced; subsequently, for any user upgrading from the Windows 10 Creators Update via Windows Update, it will be 25% smaller in size.
Additionally, Microsoft claims that it has increased the number of Windows 10 devices tested before the roll-out process began for the Fall Creators Update. The company believes that this approach ensures the "highest quality update experience" for all consumers.
Some will still question the reliability of the testing and roll-out process, and perhaps rightly so, as major issues like missing apps still plague users who installed the Fall Creators Update in the past few days. At the very least, a phased roll-out does give Microsoft a chance to fix bugs like this before its work reaches the masses.
