After installing the cumulative update KB4571756, the system version number rose to Build 19041.508. After the upgrade, the user can enter the “Winver” command in the Start menu to view the version number.

This cumulative update introduces several notable improvements, starting with security improvements. Security is improved when using input devices such as mice, keyboards, styluses, and Windows basic operations. More importantly, it improves the security of storing and managing files in the Microsoft Office Productivity Suite.

The cumulative update also fixes critical vulnerabilities in user agents and HTTP-based intranet servers. Microsoft explains in its update log:

Fixed security vulnerabilities for user agents and HTTP-based intranet servers. After this update is installed, HTTP-based intranet servers cannot detect updates by default using user agents.

If the client does not have a system agent configured, scanning using these servers will fail. If you must take advantage of a user agent, you must configure the behavior using the Windows Update policy “Allow the user agent to be used as a back-up if detection fails using a system agent.”

This change does not affect customers who use transport layer security (TLS) or secure socket layer (SSL) protocols to protect their Windows Server Update Service (WSUS) servers. For more information, see “Ensuring customers remain secure with changes scanned for Windows Server Service (WSUS) servers.”

In this cumulative update, security fixes have also been brought to core components such as Windows Kernel, Windows Storage and File System, and the Microsoft Script Engine.

There is a known issue in this cumulative update, but this is not a new issue and exists in previous releases. Microsoft explains.
