Windows Copilot Preview is now available on Dev Channel with the build number 23493

Last month at the annual Build conference, Microsoft introduced Windows Copilot for Windows 11. Although, it was already available for users running on Windows 11 Insider Preview Build 23481 or newer with ViveTool. Today, Microsoft officially rolls out the Windows Copilot Preview to users on the developer channel with the build number 23493.

If you are a developer tester in Windows Insider Preview Program, then your PC will receive the new update with Windows 11 Insider Preview Build 23493.1000 (rs_prerelease) build number. Just like the preview updates, you can quickly update your system to the new build and try out the Copilot preview along with the other features.

Windows Copilot preview isn’t the only change coming with today’s release. The update brings the all-new Settings app homepage, better support to restore apps, new volume mixer now available in Quick Settings, Narrator natural voices in Japanese and English (Great British), and more.

Windows Copilot Preview is the key attraction of today’s update. Microsoft said, “This first preview focuses on our integrated UI experience, with additional functionality coming down the road in future previews. To use Copilot in this flight you must have Windows Build 23493 or higher in the Dev Channel, and Microsoft Edge version 115.0.1901.150 or higher.”

Talking about the new Settings app, then the homepage gets a number of shortcuts including recommendations, cloud storage, account recovery, personalization, Xbox, Microsoft 365, and more.
