Microsoft is testing a new recovery tool for Windows 11 that can bring a completely unbootable PC back to life using nothing but an internet connection.
The feature, called Cloud Rebuild, officially rolled out on July 6, 2026, alongside four new Windows 11 Insider Preview builds spanning both the current and 26H1 development channels, including Experimental Preview Build 26300.8772. It was first introduced at Microsoft’s Ignite developer conference in November 2025 as part of the company’s broader Windows Resiliency Initiative.
Unlike the existing “Reset this PC” option, which only works if Windows can still start up, Cloud Rebuild is designed for the worst-case scenario a machine that won’t boot at all. It 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 integrity of the installed operating system.
To get started, you’ll need to dive into the Windows Recovery Environment and pick Troubleshoot, then Cloud rebuild. Since the whole point is pulling everything fresh from Microsoft’s servers instead of relying on anything stored locally, you’ll need to be online either plugged into Ethernet or connected to a Wi-Fi network before the process can even begin.
Once it kicks off, Windows will show you exactly what you’re about to install: the build, edition, and language, so you can double-check everything lines up before committing. Say yes, and there’s no turning back the drive gets wiped clean, taking your files, accounts, apps, and settings along with it. Only data already saved to cloud services such as OneDrive survives the process. Notably, there’s currently no “keep my files” option like the one available in the standard reset tool this is strictly a clean-slate rebuild.
Because of that data loss, Microsoft is currently pitching the feature mainly at IT administrators managing multiple devices, rather than everyday home users.
What’s new since the initial preview
Industry analysts note this could mark a bigger shift in how Windows recovery works long-term. Local recovery partitions typically eat up 5 to 15 GB of disk space on every device. If cloud-based rebuilding proves reliable, that space requirement could eventually disappear, letting device makers reclaim storage or offer cheaper, lower-storage machines.
There’s also talk that Cloud Rebuild might eventually work hand-in-hand with Quick Machine Recovery. The idea is that if your PC starts acting up, it could first try to fix itself automatically, and only reach for Cloud Rebuild as a last resort no button-pressing required on your end.
Microsoft isn’t stopping here, either. Alongside Cloud Rebuild, the company is also building out a feature called Point-in-Time Restore, which basically lets you turn back the clock on a broken system to a point when everything was still running fine. Between the two, it’s clear Microsoft is trying to cut down on the headaches that come with failed updates, driver clashes, and corrupted files.
For now, though, this is still an Insiders-only feature, and there’s no set timeline for when everyone else will get it. Going by how Microsoft usually handles these rollouts moving from Dev to Beta to Release Preview it’s reasonable to guess this could land sometime later in 2026 or push into 2027. But as always with preview features, nothing’s set in stone until Microsoft says it’s ready.
