Windows 10 KB5017380 preview update released with new FIDO2 features



Microsoft has released the optional KB5017380 Preview cumulative update for Windows 10 20H2, Windows 10 21H1, and Windows 10 21H2.

This update includes numerous bug fixes and enhancements, including a new FIDO2 and Windows Hello authentication features.

The KB5017380 cumulative update preview is part of Microsoft’s September 2022 monthly “C” update, allowing admins to test upcoming fixes released in the October 2022 Patch Tuesday.

Unlike Patch Tuesday cumulative updates, the “C” preview updates are optional and do not include security updates. However, If you run a Windows Insider build, the preview update will be installed automatically.

Windows users can install this update by going into Settings, clicking on Windows Update, and manually performing a ‘Check for Updates.’

As this is an optional update, you will be asked whether you wish to install it by clicking on the ‘Download and install’ link, as shown in the image below.
