Overview

This cumulative update for Windows 11, version 25H2 and 24H2 (KB5079473), includes the latest security fixes and improvements, along with non-security updates from last month's optional preview release. The update makes quality improvements to various Windows components, including Secure Boot, File Explorer, Windows Defender Application Control, and Windows System Image Manager. It also includes a servicing stack update to improve the reliability of Windows updates.

General Purpose

The key improvements in this update include:- Secure Boot: The update includes additional high confidence device targeting data to increase the coverage of devices eligible to automatically receive new Secure Boot certificates. This helps maintain a controlled and phased rollout of the new certificates.- File Explorer: The update improves the reliability of File Explorer search when searching across multiple drives or 'This PC'.- Windows Defender Application Control (WDAC): The update improves how WDAC handles COM objects allowlisting policies, ensuring COM objects are allowed as expected.- Windows System Image Manager: The update improves the reliability of choosing trusted catalog files by adding a warning dialog to confirm the file is from a trusted source.The update also includes AI component updates for Image Search, Content Extraction, Semantic Analysis, and Settings Model, though these are only applicable to Windows Copilot+ PCs and will not install on standard Windows PCs or Servers.

General Sentiment

The general sentiment around this update seems to be positive, with the improvements to Secure Boot, File Explorer, WDAC, and System Image Manager being well-received. However, there have been some reported issues, including a known problem with signing in to Microsoft accounts for certain apps like Teams Free, OneDrive, Edge, and Copilot. Microsoft has acknowledged this issue and provided a workaround, stating that the problem may resolve itself after restarting the device while connected to the internet. They have also noted that the issue does not affect Azure Active Directory or Entra ID authentication.Overall, the update appears to be a solid security and quality-of-life improvement for Windows 11, though the Microsoft account sign-in issue is a notable downside that Microsoft is working to address.

Known Issues

  • Signing in with a Microsoft account might fail for Microsoft Teams Free and other apps, even when the device has a working internet connection. This issue is addressed in KB5085516.
