If your Windows 10 device hasn’t updated to the newest Fall Creators Update, don’t worry, you’ll get it. It’s by design. Microsoft has implemented a phased rollout approach to the release of their updates.
The Fall Creators Update begins rolling out to newer devices tested by us and our device partners. By starting with machines which we believe will have the best update experience, we are able to get focused feedback on application compatibility and how Windows works with the rich ecosystem of available peripherals like Bluetooth devices or cameras. Additionally, we closely monitor feedback from fans and early adopters, through programs like Windows Insiders and Windows Insider for Business, in addition to feedback from our OEM device partners, and customers like you! This helps us determine when to accelerate the release to additional devices. We repeat this process until all compatible devices running Windows 10 worldwide are offered the Fall Creators Update.
