Windows Autopilot is a service that streamlines the deployment of new Windows 10 PCs. This process can be done when the end user logs on to Microsoft 365 Business Premium for the first time—without IT ever touching the device—by leveraging the centralized management controls of Microsoft 365 Business Premium. You can also use Windows Autopilot for existing PCs that are running Windows 10 Professional Creators Update (or later) and have been factory reset. Details about Windows Autopilot can be found in this June 2017 blog post.
