Microsoft Win11 Adds 'Cloud Rebuild' Feature, Allowing System Reinstall Without a USB Drive

Microsoft's Win11 now includes a 'Cloud Rebuild' feature that lets users reinstall the system on a damaged PC without preparing a USB drive, downloading the system and device drivers via Windows Update even if the computer cannot boot normally.

IT之家 October 29 news, according to tech media Windows Central’s report today, Microsoft’s Win11 system has now added a “cloud rebuild” feature, allowing users to reinstall the system on a computer with a damaged system without needing to prepare a USB drive.

IT之家 learned from the original report that this feature has been rolled out in the optional update KB5127936 and is expected to be pushed to all users in the future. It can download the system and device drivers via Windows Update, completely independent of the existing system. Even if the computer cannot boot into the system normally, users can still directly reinstall the system.

In addition, this feature requires users to connect the computer to the internet and to a power source. For some users, cloud rebuild is expected to save the trouble of creating a USB recovery drive in advance. Even if the computer suffers a severe failure, Windows can download the system directly from Microsoft’s servers.
