Microsoft has introduced Cloud Rebuild, a recovery option for Windows 11 that can wipe and reinstall the operating system by pulling a fresh image and drivers from Windows Update, even when the system refuses to boot. Ships with optional preview update KB5127936 released October 28 for Windows 11 25H2 and 26H2, rolling out gradually. If Windows loads, the option appears under Settings > System > Recovery as "Rebuild PC." If the system fails to boot, Cloud Rebuild appears in the Windows Recovery Environment (WinRE) under the Troubleshoot menu.
Unlike the existing "Reset this PC" Cloud download mode, Cloud Rebuild grabs drivers and does not depend on the installed Windows copy being intact. The system drive reformats, wiping apps, settings, user accounts, and local files, while only data synced to services like OneDrive survives. A sanitize mode securely erases the drive before reinstallation, and IT admins can initiate rebuilds remotely via the Recovery CSP.
The PC must connect online from WinRE using a manufacturer-included network driver. This same update allows WinRE to reuse saved Wi-Fi profiles. Microsoft notes the rebuild fails if device drivers are not published on Windows Update, and acknowledges WinRE has had reliability issues, such as an October 2025 update leaving keyboards and mice unresponsive.
