The WHQL process ensures that hardware or software approved by Microsoft operates smoothly and correctly on Windows 10. Many of us have seen logos or 3D stamps with accompanying content indicating Windows certification.

When developers or hardware manufacturers surpass WHQL certification, they can utilize these certificates on their products and in their advertisements.

During the release of new hardware or Windows 10 updates, Microsoft and OEMs announce the latest certified hardware. All this hardware undergoes certification and is awarded WHQL certificates for Windows.

2. WHQL Drivers.

In addition to hardware and software, Microsoft runs the Test Signature Program for Drivers. Unless signed by Microsoft, installation of these drivers is not recommended. However, intentionally installing unsigned drivers will prompt a warning.

Windows Update exclusively downloads drivers with WHQL certification. Microsoft collaborates with key OEMs such as Asus, NVIDIA, ... to ensure drivers function accurately on the current version of Windows 10 and future versions.

Furthermore, the program allows independent hardware providers to participate. They can submit driver packages for trial signing. This program is specific to a particular Windows version. After the testing process concludes, the results must be sent back to Microsoft.

3. Are WHQL Certifications Visually Important and Necessary?

The answer is no. Many OEMs ensure their software and hardware perform well on Windows 10. For instance, manufacturers store driver files on their official websites, enabling users to download and install them.

In case of any errors or issues, if you trust the OEM and the installation file, you can opt to disable signature enforcement.

This option is located in the Advanced Boot Menu =>Enable Test Signing Mode =>Disable Device Driver Signing.
