Windows 11 can now reinstall itself without a USB drive, even when the OS won't boot. Microsoft's new Cloud Rebuild recovery option is rolling out to Insiders in Experimental Preview Build 26300.8772, marking a meaningful upgrade to how users recover from catastrophic system failures.
First teased at the Ignite conference in November 2025, the feature performs a full OS reinstall by downloading both the Windows image and device drivers from Windows Update. That means no hunting for a USB installation drive, no custom recovery image, and no relying on whatever's left of the current OS to make the process work.
"Unlike Reset this PC, Cloud rebuild downloads both the target Windows image and the device's drivers from Windows Update, so the device comes back fully functional without USB media, without a custom image, and without depending on the health of the currently installed OS," Windows Insider Communications Lead Stephen Lines said.
It operates from the Windows Recovery Environment (WinRE), accessible when the system can't start at all. Users navigate to Troubleshoot > Recovery and uninstall, then select Cloud rebuild. The tool shows the target build, edition, and language before proceeding, and it warns about data loss upfront.
Unlike Reset this PC, there is no option to keep apps or files. The feature is one piece of a larger push Microsoft calls the Windows Resiliency Initiative. The company also announced Point-in-Time Restore (PITR), which lets admins roll back a system to an earlier healthy snapshot within minutes.
PITR began rolling out in June via the KB5095093 preview cumulative update for 24H2 and 25H2. Microsoft also tested an updated version of Quick Machine Recovery (QMR) last November, a tool that resolves boot failures remotely by sending crash data to Microsoft, which can remove buggy drivers or updates without physical access to the device.
Alongside the new recovery tool, Build 26300.8772 brings other changes. Settings backup and restore will enable by default starting in version 26H2 for eligible Microsoft Entra joined or hybrid joined devices, automatically saving user settings and Store app lists. Admins can override the default, and restore remains opt-in.
The Account Control flyout gets a subscription badge and cleaner layout. The Bluetooth quick settings page now supports gamepad navigation. And the search box grew by 4 pixels, a visual tweak that may help on high-DPI displays.
Cloud Rebuild is currently available only to Windows Insiders in the Experimental channel.
