Introducing Cloud Rebuild recovery feature
Using this feature, IT administrators and end users can easily restore a clean, known-good state by performing a full operating system reinstall. Cloud rebuild downloads both the target Windows image and the device’s drivers from Windows Update, so the device comes back fully functional, without USB media, without a custom image, and without depending on the integrity of the installed operating system.
Once the rebuild has been completed, end users have the ability to configure OOBE options. For managed devices, you can re-provision automatically through Windows Autopilot, Microsoft Intune, Backup for Organizations, and OneDrive.
