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.

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.
After installing this update, Windows 10 20H2 will be updated to build 19042.2075, Windows 10 21H1 will be updated to build 19043.2075, and Windows 10 21H2 will be updated to build 19044.2075.
