In a blog post by John Cable, vice president of program management, maintenance and delivery for Windows, the next features coming in the next major update for Windows 10 are briefly outlined.
The goal of the 21H1 update is to improve security, remote access and quality. The most important feature coming to Windows 10 is the ability to set a default external webcam for Windows Hello facial authentication. This is especially useful when you’re using a mobile computer that already has a built-in Windows Hello webcam but you may have it docked to a desktop monitor and want to connect with your face using an external camera.

Windows Defender will see an update that will speed up the performance of Application Guard. In addition, Defender will see the opening hours of optimized documents. Also fixed an issue that caused a delay when opening a Microsoft Defender Application Guard Office document.
The Windows Management Instrumentation Group Policy service will update its performance to support more scenarios of working remotely, online with more people working remotely.
Users who participate in the Beta Insider program are eligible to download the 21H1 update now as long as they are activated.
