  • The December Patch Tuesday is now available for Windows 11 as build 22631.2861 and 22621.2861 (KB5033375) for versions 23H2 and 22H2.
  • The December 12 update includes new changes for Copilot, Spotlight, notifications, and a slew of fixes and improvements.

Microsoft is releasing the update KB5033375 for Windows 11 23H2 and version 22H2 as the final Patch Tuesday update on December 12, 2023, with changes and several fixes and improvements.

The update KB5033375 bumps the version number to build 22631.2861 for version 23H2 and 22621.2861 for version 22H2 and, according to the official changes, this release includes miscellaneous security improvements as well as the changes and fixes previously available with the preview update KB5032288, which the company released December 4, 2023.

In this release, Copilot works on multiple displays, meaning the chatbot will now appear on the display you invoked on a multi-monitor setup. It brings Copilot to the “Alt + Tab” interface as another app, and now you can ask Copilot for help ten times in a local account without being signed in. After that, you must sign in with a Microsoft or Azure AD account to continue using the chatbot.

Microsoft is making changes, allowing the Spotlight feature to be set as the default background. This will happen if the desktop wallpaper is set to the default image or using a solid color.

The update KB5033375 also rolls to account-related notifications for Microsoft accounts in Settings’s “Home” page and the “Start” menu. According to the company, you will be able to manage these settings from Settings > Privacy & security > General.

The early preview of this rollout (KB5032288) noted that version 23H2 would also receive changes to comply with the Digital Markets Act in the European Economic Area. However, the official release notes for December 12 don’t say whether users in one of the EU regions will get these changes today.

Also, Microsoft is rolling out the update KB5033369 (build 22000.2652) for Windows 11 21H2. The update adds the recent man-made landmass outside of Rotterdam to the shape files for the Netherlands time zone. In addition, this update enables Conditional Access (CA) scenarios for Microsoft Defender for Endpoint (MDE).

It’s important to note that no optional update will be made available in December. The company will resume updates in January 2024, and the last optional update for Windows 11 22H2 will arrive in February 2024. However, security updates will continue through October 2024.
