Starting in July 2020, there will no longer be optional, non-security releases (known as "C" releases) for this operating system. Operating systems in extended support have only cumulative monthly security updates (known as the "B" or Update Tuesday release). Verify that** **you have installed the required updates listed in the **How to get this update** section before installing this update. WSUS scan cab files will continue to be available for Windows Server 2008 SP2. If you have a subset of devices running this operating system without ESU, they might show as non-compliant in your patch management and compliance toolsets. ## **Improvements and fixes** This security update includes quality improvements. Key changes include: * Changes the default privilege requirement for installing drivers when using Point and Print. After installing this update, you must have administrative privileges to install drivers. If you use Point and Print, see [KB5005652](<https://support.microsoft.com/topic/873642bf-2634-49c5-a23b-6d8e9a302872>), [Point and Print Default Behavior Change](<https://aka.ms/PointPrintMSRCBlog>), and [CVE-2021-34481](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34481>) for more information. * Addresses an issue in which Smart Card Authentication (PIV) fails on non-RFC compliant printers and scanners requiring smartcard authentication.
