At the same time, it is important to understand that the update is a “service” update, ie. does not carry new functionality. Its only task is to enable the features that the developers have already laid out.
These include, for example, the ability to receive important notifications when focus support is enabled.
Interestingly, for most users, this update is optional. However, if you have installed Windows 10 older than 20H1, installing the update will be no different than installing the cumulative update and will take much more time accordingly.
