Windows 11 Insider Preview Build 23493 finally arrived for Dev insiders

Microsoft has just released Windows 11 Insider Preview Build 23493 for insiders in the Dev channel. And, as usual, there are a lot of exciting updates in the pipeline. 

The highly anticipated feature Windows Copilot has been generating significant buzz for quite some time, and the latest development within this very build indicates that we are nearing its official release. In this particular build, Redmond officials provide users with an early glimpse of the integrated UI experience for the AI assistance tool through a controlled feature rollout.

“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.,” says Microsoft.

The feature will be conveniently located as a sidebar anchored to the right side, making it readily accessible whenever you require its assistance.

Besides, we’ve also seen a nice rejuvenation within the Settings homepage. It now showcases interactive cards, grouped according to commonly accessed functions, with a maximum of seven cards. This updated design offers users a glimpse of recommended settings, cloud storage options, account recovery methods, effortless personalization features, and more. 

The new Settings homepage provides a user-friendly interface that simplifies navigation and enhances the overall experience by conveniently presenting important and frequently used functions in an organized manner.
