This update addresses security issues for your Windows operating system.

Improvements

This security update includes quality improvements. When you install this KB:

This update supports daylight saving time (DST) changes in Israel.
This update addresses an issue that affects remote procedure calls (RPC) to the Win32_User or Win32_Group WMI class. The domain member that runs the RPC contacts the primary domain controller (PDC). When multiple RPCs occur at the same time on many domain members, this might overwhelm the PDC.
This update addresses an issue that affects the LanmanServer Service. It stops working in clusters that do not have an Administrative Access Point. These are also known as AD-Detached Clusters. They are recommended for Microsoft Exchange on some versions of Windows. To learn more, see Database availability groups.
This update addresses an issue that affects authentication. Using a smart card to join or rejoin a computer to an Active Directory domain might fail. This occurs after you install Windows updates dated October 2022 or later. For more details, see KB5020276.

If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.
