Download Windows 10 Cumulative Updates For August 2021 (KB5005033)

On this August Patch Tuesday of 2021, a new cumulative update from Microsoft, comes with important fixes and updates to all the Microsoft products including Windows 10. The latest update finally fixes the PrintNightmare vulnerabiligy (CVE-34527) which has been haunting Windows users for quite sometime. Basically, the default installation privilege requirement for printers has been changed.

Since these are important updates, they should be installed automatically if the automatic update is enabled on your computer.

As always, we recommend waiting for a while and getting a backup of your important files before installing the updates. There is no guarantee from Microsoft that the updates will be installed smoothly on the computer. Although Microsoft does extensive testing before releasing the updates, it is possible that the update may make your computer unusable.

In this article, we will talk about Windows 10 cumulative updates for August 2021, KB5005033 which covers Windows 10 Version 21H1, 20H2 and 2004.

KB5005033

After installing this update, all users who want to install the printer will have to have administrative privileges on the computer to continue. This is mainly to make sure that the PrintNightmare vulnerability is fixed once and for all.

In an article about how to manage the new Point and Print default driver installation behavior, Microsoft states:

Today, we are addressing this risk by changing the default Point and Print driver installation and update behavior to require administrator privileges. The installation of this update with default settings will mitigate the publicly documented vulnerabilities in the Windows Print Spooler service. This change will take effect with the installation of the security updates released on August 10, 2021 for all supported versions of Windows, and is documented as CVE-2021-34481.

This change may impact Windows print clients in scenarios where non-elevated users were previously able to add or update printers. However, we strongly believe that the security risk justifies this change. While not recommended, customers can manually disable this mitigation with a registry key, which is outlined in the following KB Article:

Additionally, an issue has been resolved that prevents Game Mode and power plans from working properly, resulting in lower frame rates and reduced gaming performance. 

Also, a problem where a network device in File Explorer would lose focus when a new network device is mapped has been resolved.  

Other fixes and quality improvements include the following:

  • When using Point and Print, the default privilege requirement for installing drivers has been changed. In order to install drivers after installing this update, you must have administrative privileges.
