But that won’t be the case this time, and 21H1 will arrive with a rather limited set of features.Microsoft will compensate for the same by releasing a bigger 21H2 update in the second half, which is currently known as Sun Valley. It’s expected to bring some major changes that users are waiting for the last few years.Windows 10 21H1 Features: What’s Inside The Latest Windows Update?1. External webcam support for Windows HelloWindows Hello is a preloaded security feature in Windows 10 that allows users to sign in using a pin, fingerprint recognition, or facial recognition.Existing installations of Windows 10 only allow the internal camera to be set as default for Windows Hello. But with the latest 21H1 update, you can also set the external camera as the default device for Windows Hello.This will help in case you sit at a distance from your machine and use a webcam to make video calls. Also, desktop users who can use an external webcam only would benefit from the new addon.2. Better document load timesMicrosoft has made some performance improvements to the Windows Defender Application Guard, which optimizes the load times for documents.Application Guard is a security feature that uses hardware-based isolation to prevent attacks on users’ devices. For example, it works with Microsoft Office apps and opens untrusted files in an isolated Hyper-V container. The feature is available on Windows 10 Pro, Enterprise, and Education editions.3. Improvements to Windows Management Instrumentation (WMI) Group Policy ServiceRedmond says it has given a performance update to the WMI (Windows Management Instrumentation) Group Policy Service, which will improve remote work scenarios. For example, it has fixed a heap leak issue with the WMI service that comes up when security settings are applied to the WMI namespace permissions.To recall, WMI comprises a set of extensions to the Windows Driver Model. It provides a Powershell sub-system that can be used to manage both local and remote Windows PCs and servers using VB scripts.4.
