Windows 11 KB5070773 (OS Builds 26200.6901 and 26100.6901) Out-of-band released

Microsoft has released an out-of-band update (KB5070773) for Windows 11 25H2 and Windows 11 24H2. This cumulative update addresses quality improvements and includes security fixes from the October 14, 2025, security update (KB5066835). The latest release also resolves a significant issue that was affecting USB devices in the Windows Recovery Environment (WinRE) after installing the aforementioned security update.

Users may recall that the October 14, 2025, security update caused problems with USB devices such as keyboards and mice not functioning properly within WinRE. Fortunately, this out-of-band update has successfully addressed this issue, allowing users to navigate recovery options within WinRE using their USB peripherals.

In addition to resolving this pressing problem, the release updates several AI components to improve overall performance and functionality. The updated AI components include Image Search (version 1.2509.1022.0), Content Extraction (version 1.2509.1022.0), Semantic Analysis (version 1.2509.1022.0), Settings Model (version 1.2509.1022.0), and Windows 11 servicing stack update (KB5067360) with version 26100.6893.

The servicing stack is a crucial component that enables devices to receive and install Microsoft updates reliably. This latest update makes quality improvements to the servicing stack, ensuring users have a robust and reliable framework for installing future updates.

Unfortunately, this release is not without its known issues. Some Digital TV and Blu-ray/DVD apps might experience problems playing protected content after installing the August 29, 2025, Windows non-security preview update (KB5064081), or later updates. This issue can cause copyright protection errors, frequent playback interruptions, unexpected stops, or black screens in certain applications that use Enhanced Video Renderer with HDCP enforcement or Digital Rights Management (DRM) for digital audio.
