Nvidia has rolled out a crucial Nvidia GeForce Security Update Driver 474.64 WHQL for Windows 10, 11, aimed at addressing security vulnerabilities within its GeForce GPUs. This specific release is designated for graphics processing units (GPUs) that have transitioned out of active support for both Game Ready Drivers and Nvidia Studio Drivers. This article delves into the details of this security update, its significance, and the technical aspects surrounding Nvidia’s driver ecosystem.
Understanding the Purpose of the Security Update
The primary objective of the Nvidia GeForce Security Update Driver 474.64 WHQL for Windows 10, 11 is to patch identified security flaws that could potentially expose systems to various threats. These vulnerabilities, if left unaddressed, could be exploited to compromise system integrity, leading to unauthorized access, data breaches, or other malicious activities. Nvidia’s commitment to security necessitates the release of such updates, even for older GPUs, ensuring that users are protected against known risks.
DCH vs. Standard Drivers: A Clarification
A recurring question among Nvidia users revolves around the distinction between DCH (Declarative Componentized Hardware supported apps) and standard display drivers. Functionally, there’s no performance difference between the two. The key difference lies in the packaging and installation process. DCH drivers are designed to align with Microsoft’s Universal Driver model, introduced with Windows 10.
- DCH Drivers: These drivers are smaller in size and typically install faster than standard drivers. They rely on the operating system to manage certain components, adhering to Microsoft’s modern driver framework.
- Standard Drivers: These drivers are the traditional type, encompassing all necessary components within the driver package itself.
DCH Drivers in Detail
DCH drivers represent a fundamental shift in how drivers are packaged and distributed. With the introduction of Windows 10, Microsoft aimed to create a more streamlined and consistent driver experience through the Universal Driver model. DCH drivers are a part of this initiative. They are declarative, meaning they rely on INF files to declare hardware characteristics; componentized, indicating a separation of core components from optional customizations; and hardware supported apps, referring to the integration of hardware-specific applications.

Operating System Compatibility
Nvidia DCH display drivers are compatible with Windows 10 x64 April 2018 Update (v1803, Build 17134) and all subsequent versions. This ensures that users running relatively recent versions of Windows 10 can leverage the benefits of DCH drivers.
Installation Considerations
One of the most common concerns among users is the compatibility between standard and DCH drivers. Nvidia has addressed this concern directly:
- Installing DCH over Standard: Yes, Nvidia DCH display drivers can be installed directly on top of existing Nvidia standard display drivers. The installation process handles the necessary transitions seamlessly.
- Installing Standard over DCH: Installing standard display drivers released on or after December 6, 2019, will initiate a clean installation, effectively removing the previous DCH driver before installing the standard driver. However, if you’re attempting to install a standard driver version released before December 6, 2019, it’s recommended to manually uninstall the existing DCH driver first to avoid potential conflicts.
Determining Your Driver Type
If you’re unsure which type of Nvidia driver is currently installed on your system, you can easily find out by following these steps:
- Open the Nvidia Control Panel.
- Select "System Information" located in the bottom-left corner.
- Locate "Driver Type." The text following this label will indicate whether you have a DCH or Standard driver installed.
What’s New in Driver 474.64
The key element to note here is that this is a security update. In general, this means the Nvidia GeForce Security Update Driver 474.64 WHQL for Windows 10, 11 does not come with performance improvements or new features but, instead, focuses on fixing security vulnerabilities.
Supported Products
Since the original article doesn’t list any supported products, it’s best to assume this driver is for older, out-of-support GPUs. Nvidia does not publicly state which specific older GPUs are supported by this security update driver, so users with older GPUs that are no longer receiving Game Ready or Studio Driver updates should check to see if this driver is compatible with their hardware.
Why Security Updates Matter
It’s imperative to install the Nvidia GeForce Security Update Driver 474.64 WHQL for Windows 10, 11 as soon as possible. Security updates are crucial for maintaining the integrity and security of your system. By addressing vulnerabilities, Nvidia helps prevent potential exploits that could compromise your data and system performance. Regularly updating your drivers is a fundamental aspect of responsible computer maintenance.
