Windows 11 Kb5072033 & Kb5071417 Cumulative Updates Released

Microsoft has released Windows 11 KB5072033 and KB5071417 cumulative updates for versions 25H2/24H2 and 23H2 to fix security vulnerabilities, bugs, and add new features.

Today's updates are mandatory as they contain the December 2025 Patch Tuesday security patches for vulnerabilities discovered in previous months.

You can install today's update by going to Start > Settings > Windows Update and clicking on 'Check for Updates.'

You can also manually download and install the update from the Microsoft Update Catalog.

This is the third 'Patch Tuesday' release for version 25H2, but as it's based on version 24H2, there are no exclusive or special changes. You'll get the same fixes across the two versions of Windows 11.

After installing today's security updates, Windows 11 25H2 (KB5072033) will have its build number changed to Build 26200.7462 (or 26100.7462  in case of 24H2), and 23H2 (KB5068865) will be changed to 226x1.6050.

The biggest highlight of the update is the dark mode support for dialogs in File Explorer and new Virtual Workspaces settings for managing features like Sandbox:

[Advanced Settings] New! You can now turn on Virtual Workspaces in Advanced Settings. Virtual Workspaces allow you to enable or disable virtual environments such as Hyper-V and Windows Sandbox. To access Virtual Workspaces, go to Settings > Systems > Advanced.

[Desktop Spotlight]  New!  When Windows Spotlight is set as your desktop background (Settings > Personalization > Background), the context menu now includes two options: Learn more about this background and Next desktop background.

New! File Explorer now offers a more consistent dark mode experience. Key actions such as copy, move, and delete dialogs have been updated in both default and expanded views. Progress bars and chart views now align with the dark theme to improve readability. Confirmation dialogs for actions like skip, override, and file selection, along with multiple error dialogs, have also been refreshed for a cohesive look.
