Build 23506 for Windows 11, according to the official changes, introduces the first public preview of the Windows Copilot AI chatbot to everyone, not only for a select group of users like with the previous build. Also, this flight rolls out improvements for Windows Hello for Business, warnings when copying and pasting unsafe passwords, and local file sharing.

The new Outlook app is the new default on Windows 11, and the development team is trying a few changes to the experience after completing the out-of-box experience (OOBE). Also, you can now configure your backup preferences in the second-chance out-of-box experience (SCOOBE)

Windows 11 build 23506 new features

Here are all the new features and improvements for the latest release of Windows 11 in the Dev Channel:

File Sharing

On build 23506, Windows 11 introduces various improvements for the interface to share files with others. For example, the interface has been redesigned to match the design language of Windows 11. You will now find a search box so you can search for contacts across Outlook to share a file. Instead of a dropdown, you will see a button to turn on the feature. And your computers will be at the top of discovered devices under “Nearby Share.”

Furthermore, files will transfer faster using Wi-Fi Direct, and the company added “Share” to the context menu in File Explorer, in addition to having the share icon at the top of the context menu.

Security changes

As part of the Windows Hello for Business, Windows 11 build 23506 includes a new “EnablePasswordlessExperience” policy that promotes a user experience on AAD-joined computers for core authentication scenarios without requiring a password. 

Once the policy is configured, it removes passwords from the user experience, both for device login as well as in-session auth scenarios like password managers in a web browser, “Run as” administrator or as a different user scenario, and User Account Control (UAC). Users will navigate through their core authentication scenarios using Windows Hello for Business in place of passwords.

Also, Microsoft is updating the Enhanced Phishing Protection in Microsoft Defender SmartScreen to show a warning when copying and pasting an unsafe password. This is in addition to showing a warning when typing a password.

Out-of-box experience

The software giant is also updating the experience after completing the out-of-box experience. 

If you choose “Development Intent” in the “Let’s Customize Your Experience” page during the out-of-box experience, Dev Home will be automatically launched on the computer after logging in.

In the case that you choose “Development Intent,” the Get Started app will be automatically launched after logging in and reaching the desktop for the first time after setup. 

Or if you choose to “Restore,” the Get Started app will automatically start after you log into your device for the second time after completing the out-of-box experience. The Get Started app will show you a personalized flow to learn key apps and settings, notify you that the system has been restored on your device, and show you how to access your restored apps on the Start menu or Taskbar.

Other changes

Starting with the preview, the new Outlook is now an inbox app.

As part of the backup and restore experience, you can configure the backup preferences in the second-chance out-of-box experience (SCOOBE) so your apps, settings, credentials, and files are backed up in the cloud.
