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.
