What is Windows 10 WHQL
We will cover the following areas: 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 which 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 release or new Windows release, Microsoft along with OEMs announce new hardware. All these hardware are certified for Windows
WHQL Drivers
Apart from Hardware, and Software, Microsoft runs a Test Signature Program which is for drivers. Unless Microsoft signs the drivers, they are not recommended to install it. 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 make sure the drivers properly work with the current and upcoming version of 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 which is for a specific version of Windows. When the test process completes, the result has to be sent back to Microsoft.
So is it necessary to have WHQL certification?
The answer is No. The certification does leave a big impact when it comes to sales, but many OEMs do make sure their software and hardware work on Windows 10. Say, for example, manufacturers host driver files on their website, and it’s fine to download and install it. In case you do face any error, but you 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. I hope this answers your questions about WHQL.
