- The December Patch Tuesday Update arrives for Windows 10 22H2 and 21H2 as build 19045.3803 and 19044.3803 (KB5033372).
- The update KB5033372 introduces Copilot to Windows 10 and rolls out security fixes and improvements.
- Windows 10 21H2 and versions 1809, 1607, and 1507 also receive updates.
Microsoft rolls out the KB5033372 as the next update of Windows 10 22H2 and version 21H2. The update is rolling out with security fixes and the first preview of Copilot for Windows 10.
According to the announcement from the official website, the update KB5033372 bumps the version number to build 19044.3803 (21H2) and 19045.3803 (22H2), introducing the preview of Copilot in the Taskbar and making available some miscellaneous security improvements. The company notes that this update includes the fixes and improvements previously available with the preview update KB5032278, released on November 30, 2023.
For example, this Patch Tuesday Update introduces the “Get the latest updates as soon as they are available” feature in the “Windows Update” settings, adds new settings to control notifications for updates, tweaks the “news & interests” experience, and more.
Copilot will roll out through the Microsoft Controlled Feature Rollout (CFR), meaning that not everyone will receive the feature on day one. Also, the feature will be available for Windows 10 Pro and Home (version 22H2), but it’ll not be rolled out for managed devices, nor will it be available for Windows 10 Enterprise and Education editions.
In addition, the company is making available updates for older versions of the operating system, including versions 1809, 1607, and 1507.
If you prefer manually installing the November 2023 update for version 22H2 or 21H2, download it from the Microsoft Update Catalog website.
Windows 10 update KB5033372
These are the fixes and improvements rolling out for Windows 10 on December 12, 2023:
- This update adds the Copilot in Windows (in preview) button to the right side of the taskbar. This only applies to devices that run Home or Pro editions (non-managed business devices). When you select it, Copilot in Windows appears at the right on your screen. It will not overlap with desktop content or block open app windows. This is available to a small audience initially and deploys more broadly in the months that follow. To learn more, see How to get Copilot in Windows (in preview) on Windows 10 and Welcome to Copilot in Windows.
- The news & interests feature on your device is now larger! This will help you use the feature more effectively and show the content you care about most on a larger scale.
- If you use Home or Pro consumer devices or non-managed business devices, you can get some of the newest experiences as soon as they are ready. To do so, go to Settings > Update & Security > Windows Update. Set the Get the latest updates as soon as they are available toggle to on. Note that this toggle is not turned on for devices that your IT department manages unless IT configures a new policy.
- This update addresses an issue that causes IE mode to stop responding. This occurs when you have multiple IE mode tabs open.
- This update addresses an issue that affects the cursor. Its movement lags in some screen capture scenarios.
- This update addresses an issue that affects the touch keyboard. It might not appear during the out-of-box experience (OOBE).
