Release Date:

8/10/2021

Version:

Monthly Rollup

Important: Windows Server 2008 Service Pack 2 (SP2) has reached the end of mainstream support and is now in extended support. 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. 

For information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article. To view other notes and messages, see the Windows Server 2008 Service Pack 2 update history home page.

Improvements and fixes

This security update includes improvements and fixes that were a part of update KB5004305 (released July 13, 2021) and addresses the following issues:

  • 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 KB5005652Point and Print Default Behavior Change, and 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. For more information, see KB5005390.

  • This update also contains miscellaneous security improvements to internal OS functionality.

For more information about the resolved security vulnerabilities, please refer to the new Security Update Guide website.

Known issues in this update

Symptom

Workaround

After installing this update, the Encrypted File System (EFS) API OpenEncryptedFileRaw(A/W), often used in backup software, will not work when you back up to or from a Windows Server 2008 SP2 device. OpenEncryptedFileRaw will continue to work on all other versions of Windows (local and remote).

This behavior is expected because we addressed the issue in CVE-2021-36942.

Note If you cannot use backup software on Windows 7 SP1 and Server 2008 R2 SP1 or later after installing this update, contact the manufacturer of your backup software for updates and support.

After installing this update and restarting your device, you might receive the error, “Failure to configure Windows updates. Reverting Changes. Do not turn off your computer”, and the update might show as Failed in Update History.

This is expected in the following circumstances:

  • If you are installing this update on a device that is running an edition that is not supported for ESU. For a complete list of which editions are supported, see KB4497181.

  • If you do not have an ESU MAK add-on key installed and activated.

If you have purchased an ESU key and have encountered this issue, please verify you have applied all prerequisites and that your key is activated. For information on activation, please see this blog post. For information on the prerequisites, see the "How to get this update" section of this article.

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.

  • Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.
