Windows 11 Cloud Rebuild Arrives in October's Optional Update and Never Keeps Your Files
Microsoft's October 2026 non-security preview update for Windows 11 adds cloud rebuild, a reinstall that pulls Windows and your device drivers from Windows Update instead of a local recovery partition. Microsoft's own documentation is blunt about what that costs, because cloud rebuild never keeps your files. The cloud rebuild screen offers Remove files or Remove and sanitize files, with no option to keep anything.
