Overview
- Microsoft began testing Cloud Rebuild in the Windows Insider Experimental channel on Tuesday, making the feature available in Insider Preview Build 26300.8772 for hands-on trials.
- Testers launch Cloud Rebuild from the Windows Recovery Environment (WinRE) where the tool connects by Ethernet or Wi‑Fi, downloads a Windows image and drivers from Windows Update, and performs the reinstall.
- The process is destructive by design because it reformats storage and removes personal files, accounts, apps, and custom settings so users must confirm a data-loss warning and back up before using it.
- Microsoft positions Cloud Rebuild for IT and recovery scenarios as part of its Windows Resiliency Initiative alongside Point-in-Time Restore and Quick Machine Recovery, with wider rollout planned after Insider feedback.
- Cloud Rebuild builds on earlier cloud reinstall options by working when Windows is unbootable and by fetching device-specific drivers automatically so machines return fully functional without USB install media.
