Microsoft have temporary stopped the Windows Insider builds on the fast and slow ring as they switch over to the new smaller UUP updates. UUP is a way of reducing the amount of data sent down during the update process by the system checking which updates are required rather than sending down a whole build image. While Microsoft are testing the new update process on the internally no build will be available to Windows Insiders, once the builds have passed the testing criteria and are promoted to the fast ring Windows Insiders will have access to the new build via UUP.
We are getting ready to start releasing PC builds to Insiders using UUP. To prepare for this, we are going to pause all PC builds for both the Fast and Slow rings starting this evening (Friday 12/2). We will begin flighting the latest builds via UUP starting with our internal rings first then to Insiders based on each ring’s promotion criteria. We’re excited to be able to release builds for PC to Insiders using UUP! Mobile builds are not impacted by this
