Microsoft has introduced a new recovery feature for Windows 11 called Cloud Rebuild, aimed at simplifying the restoration of non-booting PCs without the need for physical recovery drives. Announced at the Ignite 2025 conference, it is available in the Windows 11 Insider Experimental Preview Build 26300.8772. Cloud Rebuild allows users to restore their PCs to a clean state by performing a full OS reinstall, downloading the necessary Windows image and drivers directly from Windows Update. This feature is designed for recovery scenarios and can be accessed even when the system is unresponsive. It may first attempt a Quick Machine Recovery, and if that fails, it will transition to a cloud-based reinstallation. To use Cloud Rebuild, users must navigate to Troubleshoot → Recovery and Uninstallation → Cloud Rebuild within the Windows Recovery Environment (WinRE), and it will erase all existing files on the computer. Currently, it is primarily aimed at system administrators, and users of Windows 11 Home may consider upgrading to Windows 11 Pro to utilize its features.
