Windows 11 Preview Adds Cloud Rebuild for Damaged PCs

Microsoft has introduced a native “Cloud Rebuild” recovery option in Windows 11 preview build 26220.9343. The feature is available through the Windows Recovery Environment (WinRE), which can launch after repeated boot failures or be opened manually through Settings > System > Recovery > Advanced startup.

With an Ethernet or Wi-Fi connection, Cloud Rebuild contacts Windows Update servers to download a Windows system image and the necessary hardware drivers, avoiding potentially corrupted local recovery files or the need to create USB installation media.

The feature lets users confirm their Windows edition, build version and system language before reinstalling the operating system. In this preview build, WinRE can also inherit saved Wi-Fi profiles, reducing the need to enter wireless credentials manually during recovery.

The article presents the capability as particularly useful when local recovery partitions or existing system files are damaged, although it does not provide independent testing or evidence of successful deployments beyond the reported feature and Microsoft’s release notes. Cloud Rebuild is described as a recovery function rather than a response to a confirmed security incident or active exploitation.

The same preview release includes a redesigned WinUI-based AutoPlay interface, support for double backslashes and quotation marks in File Explorer’s address bar, DIB desktop background files, and scheduled OneDrive backups for photos and videos on connected mobile devices. Users wanting to use Cloud Rebuild will need a supported Windows 11 preview build and network connectivity in WinRE; the article does not specify wider availability or a general release date.
