Windows 11 can now reinstall itself from the cloud — Cloud Rebuild revives dead systems without secondary boot media, wipes broken installation and downloads a fresh copy of the OS
Windows recovery gets easier.
Microsoft has finally solved one of the biggest pain points of Windows with the rollout of Cloud Rebuild. The new recovery feature can reinstall Windows 11 even when an existing Windows installation is corrupt or refuses to boot. Available as a beta through the newly released Windows 11 Insider Beta Preview Build 26220.9343, the feature is essentially a hassle-free alternative to creating a Windows installation USB drive when a PC needs to be recovered.
According to Microsoft, Cloud Rebuild is designed to restore a Windows 11 PC to a “clean, known-good state” by downloading a fresh image of Windows along with the required drivers directly through Windows Update. Unlike the existing Reset this PC functionality, it does not depend on the health of your existing Windows installation, nor does it require users to have a USB drive or custom recovery image available.
Available via the Windows Recovery Environment (WinRE), users can access it by selecting Troubleshoot > Recovery and uninstall > Cloud rebuild from WinRE. Speaking of which, Microsoft has also improved networking support in WinRE. The recovery environment can now reuse eligible Wi-Fi profiles saved within an existing Windows installation, allowing a PC to connect during recovery without requiring administrators to separately configure Wi-Fi credentials in WinRE. Once the PC is connected, Cloud Rebuild checks Windows Update for the target Windows build and downloads the required files. Users can then confirm the Windows edition, language, and build before starting the reinstall.
The only catch here is that Cloud Rebuild completely wipes the system drive, meaning that the process removes all data stored in your main installation or C: drive, including locally stored files, accounts, applications, and settings, before reinstalling Windows. Thus, it is recommended to back up all your important files either locally or using a cloud-based service before starting the process. Once the installation is complete, the PC boots into the Windows out-of-box experience, similar to a fresh installation of Windows. For admin-managed PCs using Windows Autopilot and Microsoft Intune, the system can automatically reconnect to the organization's management infrastructure and restore assigned applications, policies, and backed-up settings.
Cloud Rebuild could particularly be useful when Windows becomes too corrupted to boot normally. Instead of finding another PC, creating installation media, and manually reinstalling Windows, users can potentially perform the entire recovery process directly from WinRE. The feature is still in preview; however, we can expect a wider release later this year.

habermas Just to be sure: This is a feature that Macs and Raspberry Pis have had for years, right?Reply
EDIT: Sure enough. Macs since 2011 and Raspberry Pis since 2022. -
olaf Yeah this feature is really annoying, micro$lop does what ever it wants and ruins dual boot or recovery attempts ... It will help the non technical annoy it departments around the worldReply -
Alastor01 Interesting.Reply
But that requires at least working bootloader and WiFi / Ethernet drivers? -

thesyndrome This is definitely a step forward, but I wished it acted more like a combined SFC/ DISM command in a GUI where it checks for broken required system files and just replaces those with downloaded versions, so as not to overwrite custom installs that were stable.Reply -
S58_is_the_goat Great solution... in case an update ruins windows and you need to reinstall, it'll do it for you 😂Reply -

Windows is your only OS.

davidjkay How is this new or finally? Eg Youtube video from 6 years ago on how to install windows 10 from cloud, I remember options like this for long time. Was windows 11 so late to join the party?Reply
I remember options like this for all sorts of OS for a very long time, basically ever since most people had internet faster than dial up. It doesn't take much, eg non graphical installer with ability to use your wired network card (or later wifi card) to get a tcp/ip stack going. -
davidjkay Eg debian 3.0 in 2002 and similar distributions had network/internet from any active internet mirror, I remember sometimes it was just 1 or 2 floppy disks to get the install going. (if you run installer program from boot sector on hard drive then you risk a virus surviving and infecting new install)Reply
30 years ago if you were smart you could set up a computer to boot or install using network card with "Preboot Execution Environment" even if you had no floppies or cd drive locally. Usually back then internet megabytes cost money so usually made a local mirror and used that rather than "cloud".
