Windows HCL: What Is the Windows Hardware Compatibility List?

The Windows Hardware Compatibility List (also known as Windows HCL) is very simple, a list of hardware devices compatible with a particular Microsoft Windows operating system version.

Once a device has cleared the Windows Hardware Quality Labs (WHQL) process, the company can use a “Certified for Windows” badge, logo (or something very alike) in their advertising, and the device is acceptable to be registered in the Windows HCL.

The Windows HCL is usually just called the Windows HCL. Still, you may see it under many names like Windows Compatibility Center, HCL, Windows Compatibility Product List, Windows Logo’d Product List, or Windows Catalog.

When Should You Use the Windows HCL?

The Windows Hardware Compatibility List (Windows HCL) assists as a  handy reference when publishing hardware for a computer you wish to install a newer version of Windows OS onto.

Of course, you can usually assume that most PC hardware is compatible with an established version of Windows. Still, it’s wise to double-check for compatibility with a version of Windows that hasn’t been on the market very long.

The Windows HCL can sometimes be a helpful troubleshooting tool for specific Device Manager error codes like (Code 43) and STOP errors like BSOD (Blue Screens of Death). However, some errors that Windows shows are related to particular hardware could likely be due to a general incompatibility between that piece of hardware and Windows.

You could search for the troubled piece of hardware in the Windows HCL to check if it’s listed as incompatible with your Windows version. If so, you’d recognize that was the problem and could either replace the peripheral with a compatible model or contact the hardware manufacturer for additional information on updated device drivers or further plans for compatibility.
