When buying a Windows 11/10 PC or software for your computer, you want it to run without any problem. That’s where certification from Microsoft comes into the picture. Microsoft calls it Windows 10 WHQL or Windows Hardware Quality Labs. In this post, we will get to know about it.
What is Windows 11/10 WHQL
We will cover the following areas:
- About WHQL
- WHQL Drivers
- WHCL Certification necessity
About WHQL
WHQL process guarantees that hardware or software approved by Microsoft works well on Windows 10. I am sure you have seen logos and a 3D marker that says “Certified for Windows“. When a developer or hardware manufacturer passes the WHQL, they can use this on their products and advertise.
Many a time, during new hardware releases or new Windows releases, Microsoft, along with OEMs, announces new hardware. All these hardware are certified for Windows
WHQL Drivers
Apart from Hardware, and Software, Microsoft runs a Test Signature Program for drivers. Unless Microsoft signs the drivers, they are not recommended to install them. However, If you do, you will be warned about it. Windows Update downloads only WHQL-certified drivers. Microsoft works with significant OEMs like Asus, NVIDIA and more to ensure the drivers properly work with the current and upcoming Windows 10.
The program also allows independent hardware vendors to participate in this program. They can submit driver packages to be test-signed. The program is a kit that is for a specific version of Windows. When the test process completes, the result must be returned to Microsoft.
So is it necessary to have WHQL certification?
The answer is No. The certification does significantly impact sales, but many OEMs ensure their software and hardware work on Windows 11/10. For example, manufacturers host driver files on their websites, and it’s OK to download and install them.
If you face any error but trust the file and OEM, you can always force disable signature enforcement.
The option is available under Advanced Boot Menu > Enable Test Signing Mode> Disable Device Driver Signing.
What is the WHQL test signature program?
Before the drivers from OEM are taken to the final stage with WHQL, Microsoft offers OEMS to test sign drivers to figure out early issues. The WHQL test signature program allows the signing of drivers, which is eventually submitted for WHQL release signature. Even if the company has not patterned with Microsoft, independent hardware vendors participating in this program can submit driver packages for test-signed.
I hope this answers your questions about WHQL.
