Microsoft shipped two optional Windows 11 Preview cumulative updates today: KB5127653 for version 26H1 (build 28000.3365) and KB5127936 for versions 26H2 and 25H2 (builds 26300.9818 and 26200.9818). These non-security packages layer new features on top of the mandatory October 13 Patch Tuesday security releases. The headline changes include a fully customizable File Explorer right-click menu and a USB-free "cloud rebuild" recovery option that works even when Windows won't start. However, both updates flag a known issue with USB Audio Class 1.0 devices, so those users should hold off until Microsoft posts a fix.
