UPDATE 12/1/2023: Microsoft is making the update KB5032278 available for Windows 10 devices enrolled in the Stable Channel of the Windows Insider Program as an optional install. This is a significant update as it introduces the Copilot AI to Windows 10, in addition to a slew of new features, improvements, and fixes.
The update KB5032278 bumps the build number to 19045.3758 and, according to the official changes (Release Preview Channel announcement), brings Copilot to Windows 10, 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.
As previously rumored, Microsoft plans to bring its Copilot AI to Windows 10, and the build 19045.3758 is the update that adds the upcoming feature. If you want to be among the first users to try this feature, after installing the update KB5032278, you will have to turn on the new “Get the latest updates as soon as they are available” toggle switch on the “Windows Update” page, and then, Copilot will eventually appear on the Taskar automatically.
It’s important to note that 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.
Windows 10 update KB5032278 fixes and changes
These are all the non-security fixes, changes, and improvements available starting November 16 for Windows 10 22H2:
- 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.
- 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 adds new functionality that affects app defaults. To learn more, see A principled approach to app pinning and app defaults 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.
