Microsoft has begun testing the Cloud Rebuild recovery feature in the latest Windows 11 Insider Preview builds released for users in the Experimental channel.
First introduced at the Ignite developer conference in November 2025, Cloud Rebuild is a tool that can remotely trigger a complete system reinstall from the cloud for Windows 11 devices experiencing persistent problems or that have become inoperable.
"We're introducing Cloud rebuild, a new recovery option that restores a Windows 11 PC to a clean, known-good state by performing a full OS reinstall, even when Windows won't boot," Windows Insider Communications Lead Stephen Lines said on Monday.
"Unlike Reset this PC, 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 health of the currently installed OS."
Windows Insiders who want to test Cloud Rebuild must first install Windows 11 Insider Experimental Preview Build 26300.8772, then start the recovery process by clicking "Cloud rebuild" in the Windows Recovery Environment (WinRE) under Troubleshoot > Recovery, and finally uninstall.
