How to use Cloud rebuild to reinstall Windows 11 without USB from WinRE

• Cloud rebuild is a new Windows 11 recovery feature on version 26H2 that performs a complete reinstall using Windows images and drivers downloaded from Windows Update.
• The feature runs through Windows Recovery Environment (WinRE) and does not require a USB installer, recovery partition, or custom system image.
• Cloud rebuild erases the system drive, removing apps, accounts, settings, and locally stored files, making backups essential before starting.
• After reinstalling Windows, the PC starts the Out-of-Box Experience (OOBE), while managed devices can automatically reconnect through tools like Intune and Autopilot.
• The feature is currently available as a preview and requires internet access, WinRE support, and compatible network drivers.

Microsoft is introducing Cloud rebuild, a new recovery feature for Windows 11 that completely reinstalls the operating system directly from Microsoft’s servers. Unlike Reset this PC, which relies on files stored locally, Cloud rebuild downloads a fresh copy of Windows 11 and the necessary hardware drivers from Windows Update.

The feature is currently available as a preview for Windows 11 26H2 and is aimed primarily at network administrators, but it also benefits advanced users who need to recover a computer that can no longer be trusted after corruption, malware, or system failures.

What is Cloud rebuild?

Cloud rebuild is a new recovery feature built into the Windows Recovery Environment (WinRE) that performs a complete reinstallation of Windows 11.

Rather than relying on recovery files already stored on the computer, it downloads a fresh copy of the operating system directly from Windows Update along with the drivers needed for the device’s hardware.

During the process, the system drive is reformatted, the operating system is installed from scratch, and the computer boots into the Out-of-Box Experience (OOBE), just as if it were being turned on for the first time.

Unlike traditional recovery methods, Cloud rebuild doesn’t require a USB installation drive, a recovery partition, a custom system image, or even another computer to create installation media. As long as the device can connect to the internet from the Windows Recovery Environment (WinRE), it can download everything needed to restore Windows to a clean, known-good state.

What’s the difference between Reset this PC?

Although Windows 11 already includes Reset this PC, Cloud rebuild is designed to provide a more complete recovery experience. While Reset this PC can reinstall Windows 11 using either local recovery files or a cloud download, it still depends to some extent on the existing recovery infrastructure and doesn’t download a fresh set of hardware drivers.

On the other hand, Cloud rebuild retrieves both the installation image and compatible device drivers directly from Windows Update, allowing it to rebuild the operating system without relying on the integrity of the installed Windows installation.

Because the feature retrieves a fresh operating system image and the required drivers from Microsoft’s servers, it’s better suited for recovering devices with severely corrupted system files or damaged recovery components. In practice, Cloud rebuild offers an experience much closer to performing a clean installation from installation media, but without requiring a USB flash drive or another computer to create one.

In this guide, I’ll outline the steps to reinstall Windows 11 using the Cloud rebuild feature.

Before proceeding

Before using Cloud rebuild, the device must meet several requirements:

• Windows 11 has to be installed on compatible hardware.
• Windows Recovery Environment (WinRE) has to be enabled.
• Internet connectivity from WinRE.
• Ethernet or WPA2 Personal Wi-Fi support.
• Compatible network drivers already available inside WinRE.

Since recovery happens entirely in WinRE, Microsoft also requires manufacturers to include compatible network drivers in the recovery environment.

One important limitation is that Cloud rebuild performs a complete wipe of the system drive, including: 

• User accounts.
• Installed applications.
• Personal files stored locally.
• System settings.
• Configuration changes.

Only cloud-stored content, such as files synchronized with OneDrive, remains available after signing back in.

As a result, this feature should be considered equivalent to a clean Windows 11 installation.

Reinstall Windows 11 using Cloud rebuild

To reinstall Windows 11 using a clean installation without USB bootable media, follow these steps:

1. Open Settings on Windows 11.

2. Click on System.

3. Click the Recovery page on the right side.

4. Click the Restart now button in the “Advanced Startup” setting under the “Recovery options” section.

   

   Quick note: The Advanced Startup option in the Settings app isn’t available through a Remote Desktop Connection.

5. Click the Restart now button again.

6. Click on Troubleshoot.

7. Click the Cloud rebuild option.

   

8. Click the Continue button if the version, edition, and language are correct for your current setup.

   

9. Click the Install button after understanding the rebuild process.

   

10. Continue with the Out-of-box Experience (OOBE) to create an account and choose your privacy settings.

Once you complete the steps, Windows 11 will reinstall version 26H2 (or a later release) as a clean installation, and the computer should start normally.

How Cloud rebuild works

The recovery process starts from the Windows Recovery Environment (WinRE). Once initiated, Cloud rebuild connects the device to the internet and contacts Windows Update to determine the appropriate edition, language, and target build for Windows 11.

After that, the feature downloads the Windows 11 installation files and the compatible hardware drivers needed for the device. Cloud rebuild then formats the system drive, reinstalls the operating system, and restarts the computer into the initial setup experience, as if it were a new installation performed using a USB bootable media.

Microsoft notes that the computer may restart several times during the process, and users should keep the device connected to power and avoid manually interrupting the rebuild while Windows is preparing, downloading, or installing the operating system.

The company also notes that local administrators can initiate a rebuild using command-line tools. However, enterprise remote deployment through management solutions such as Microsoft Intune isn’t available yet. Microsoft says remote initiation will arrive in a future release.

Common Cloud rebuild known errors

Microsoft is aware of at least two errors that could occur while using this feature:

Error 0x800704C6

This indicates the device cannot reach Windows Update.

Possible causes include:

• No internet connection.
• Unsupported Wi-Fi authentication.
• Ethernet disconnected.

Currently, WinRE supports Ethernet and WPA2 Personal wireless networks.

Error 0xC1900200

This error usually indicates one of two issues:

• The computer doesn’t meet Windows 11 requirements.
• Required drivers aren’t available through Windows Update.

Microsoft specifically notes that TPM being disabled is one of the most common causes.

If TPM is enabled and the error continues, the manufacturer may not have published all necessary drivers to Windows Update.

Pureinfotech’s Take

Cloud rebuild looks like the recovery feature Windows has been missing for years. While “Reset this PC” improved recovery compared to earlier versions, it still depends heavily on the existing installation or recovery files, which can become corrupted. In many cases, I’ve found that creating a USB installer with the Media Creation Tool remains the most reliable way to recover a system.

Cloud rebuild changes that equation. By downloading both Windows and compatible drivers directly from Windows Update, Microsoft is removing several pain points that have traditionally complicated a clean reinstall. The fact that it works from WinRE also means it can recover systems even when the operating system itself is no longer working correctly.

I also think this feature fits perfectly into Microsoft’s broader effort to make Windows recovery more resilient. Over the past year, the company has introduced features, such as Quick Machine Recovery and Cloud-Initiated Driver Recovery, both designed to reduce downtime after failed updates or driver issues. Cloud rebuild feels like the next logical step, providing a straightforward way to revert a device to a known-good state without requiring external media.

That said, this isn’t a replacement for every recovery scenario. The feature still depends on a working recovery environment, internet connectivity, and drivers being available through Windows Update. If any of those components are missing, a traditional USB installation will remain the fallback. Even so, once Cloud rebuild reaches general availability, I expect it to become one of the easiest and most reliable ways to recover Windows 11 PCs, particularly for organizations managing large fleets of devices.
