Because Microsoft claims that it will no longer provide general-purpose update logs to ordinary individual users, it will only provide specific content descriptions when updates are important, so from the details of the updates provided this time, the security vulnerability fixes are explained. More important, but the functional improvement is still not clear.

This cumulative update still includes all previous updates. If you keep updating on time, only this update will be downloaded and installed. A reboot will be required after the installation is complete. Please schedule a reboot in time for the security update to work.
