Quick Settings Cast changes

The next time you open the Quick Settings (Windows key + A) to use the Cast feature, you will notice some improvements. For example, the system will suggest using Cast through a notification toast when performing multitasking activities, such as often switching between windows to complete a task or using Snap Assist to organize your screen space.

Windows 365 Boot and Switch 

Microsoft is also testing the new personal mode for Windows 365 Boot, allowing you to configure the device to boot straight into your Windows 365 Cloud PC. As part of the Windows 365 Boot experience, the company is also adding the ability for organizations to change the logo and name of “Windows 365 Boot,” and it introduces a new fail-fast mechanism so you don’t have to wait until the login fails to know that there’s a network problem.

Finally, this update makes it easier to access and manage sound, display, and other device-specific settings of their local PC directly from your Cloud PC under Windows 365 Boot.

As part of the Windows 365 Switch experience, this update improves the disconnect experience by going to Local PC > Task view > Right-click on the Cloud PC button > Disconnect.

When you switch between your respective computers, you will see the terms “Cloud PC” and “Local PC” on the desktop indicator. In addition, the Cloud PC will now display updates regarding the connection status and the connection timeout indicator while waiting on the connection screen.

Other changes

This flight also updates the Share experience to include an option to share items through WhatsApp.

Also, the Nearby Sharing page now allows you to rename your computer, giving you a more friendly name to identify the device when sharing.
