Windows 11 KB5070773 emergency update out to fix Recovery failure in Windows 11 25H2 / 24H2

Emergency Update for Windows 11

Microsoft has released an out-of-band update, Windows 11 KB5070773, to fix a broken Windows Recovery Environment (WinRE) caused by the previous update, KB5066835.

The issue arose after the October 2025 Patch Tuesday update, which installed automatically for Windows 11 24H2/25H2 versions. Tests confirmed that the keyboard and mouse no longer work in WinRE, making the recovery process unusable.

Microsoft used server-side updates to quickly reverse changes that broke localhost, but the second problem, which breaks Windows Recovery Environment (WinRE), cannot be rolled back via server-side changes.

The new update, KB5070773, is designed to address this issue and restore functionality to the Windows Recovery Environment.

Author's summary: Windows 11 emergency update fixes recovery failure.
