Finally Windows 10 20H2 is released to the public, but for all the participants in Windows Insider programme the news are “old” news 🙂 This is the beauty of being a member to the program, testing all the features and affecting the development of Windows by giving feedback to the team behind. Thanks!
First of all if you upgrade by using Windows Update this update is quite small, the upgrade is just an enablement package that enables all the new features that already exist on your recently updated Windows 10 2004 (Released in the monthly quality update October 13, 2020). This is due to Windows 2004 and 20H2 share the same core operating system/system files and the features updates will stay disabled until the enablement package/master switch is installed and activates the new features. This will make sure your restarts will be less and the upgrade will be faster. If you upgrade from an earlier version, say 1909, the enablement package cannot be used so instead it is bundled in the upgrade and the installation time will not be reduced in this scenario.
The enablement package is found here
Windows Update and Microsoft Update simply called Feature Update to Windows 10, version 20H2
WSUS will automatically synchronize the update if you enabled Product: Windows 10 and Classification: Upgrades
The Microsoft Update Catalog does not include this update
Note the prerequisites: KB4577266 and KB4579311
So how do the feature affect your end-users?

More secure biometric sign on
Windows Hello now offers added support for virtualization-based security for certain finger and face sensors which secures and isolates users biometric authentication data (Requires special hardware and documention will come later this year)
Windows Defender Application Guard and Microsoft 365 Apps and Edge
Windows Defender Application Guard(requires Windows 10 Enterprise) can now protect Microsoft 365 Apps (requires Microsoft 365 E5) and Edge with hardware isolation. So untrusted sources and documents will be opened in a virtualized container
