Laurent the first picture in the post is of the new Ux in the settings app on Windows 10 20H1. That Ux will be present in 20H1+, and there is no plan to backport to prior releases. End users acquire manual drivers on previous Windows 10 releases through the Device Manager Ux that was used to acquire Optional drivers.
The changes we've made on the HDC side in both our publishing actions, and the Ux that is displayed on the Shipping Label page was deployed yesterday. I hope this helps break it down.
All drivers published as automatic are subject to driver flighting, and gradual rollout. During these periods we are reviewing telemetry around the performance of the driver, and it's effects on overall system health. We catch a lot of driver issues this way before they hit the Windows user base writ large. From an end user perspective we believe this will result in higher quality drivers (stable, performant) being delivered, and a better ability to stay current.
We are constantly watching and learning here based on the data we see coming back from the field. We'll continue to make adjustments (as we have been all along) based on what we are seeing.
