Microsoft Pushes Out-of-Band Windows 11 Update to Fix Broken Recovery Input

The emergency patch follows an October security release that disabled USB keyboards and mice in the Windows Recovery Environment and triggered localhost failures for some developers.

Overview

  • An out-of-band update, KB5070773, is rolling out to Windows 11 versions 24H2 and 25H2 to restore input in the Windows Recovery Environment after KB5066835 broke USB mouse and keyboard control.
  • Microsoft confirmed the WinRE bug affects recovery only, with USB input working normally inside Windows, and says November’s Patch Tuesday will also carry the fix.
  • The October update also introduced a regression in HTTP.sys that disrupted HTTP/2 connections on localhost, affecting IIS and local development, which Microsoft mitigated server-side.
  • Until the fix is installed, users can avoid recovery mode, try a PS/2 keyboard or mouse, or uninstall KB5066835; manual WinRE image replacement is possible but risky and not generally recommended.
  • KB5070773 may appear as an optional download before installing automatically via Windows Update, so affected users should check for updates and apply the patch promptly.
