Microsoft is testing a new Windows 11 feature called "Cloud rebuild" designed to salvage systems that fail to boot or reset, allowing users to reinstall the operating system directly from the cloud via the recovery screen without the need for a flash drive or ISO file. The feature was discovered in an experimental Windows 11 Insider preview build, where it operates within the Windows Recovery Environment (WinRE), the dedicated system recovery mode.
A key highlight of the Cloud rebuild feature is that it goes beyond merely downloading and reinstalling the operating system; it can also fetch essential device drivers from Windows Update during the recovery process. This ensures that essential hardware, particularly Wi-Fi or LAN connections, functions immediately after installation—a critical step, as lacking internet access post-recovery prevents users from downloading further updates or drivers.

According to available data, the Cloud rebuild option will be located under the Troubleshoot menu within WinRE. When a computer enters recovery mode, users can opt for the cloud-based reinstallation, provided the machine remains connected to the internet throughout the process. While a wired LAN connection is ideal, users can select a Wi-Fi network and enter passwords directly from the recovery interface in certain scenarios.
