Microsoft plans to use machine learning in the future to improve the delivery of updates, by rolling updates out intelligently and making the update experience smoother in the process.We also started the first phase in our rollout for machine learning (ML) training, targeting devices on Windows 10, version 2004 to update automatically to Windows 10, version 21H1. We will continue to train our machine learning through all phases to intelligently rollout new versions of Windows 10 and deliver a smooth update experience.
