The Windows Hardware Compatibility List, usually just called the Windows HCL, is, very simply, a list of hardware devices compatible with a particular version of a Microsoft Windows operating system.

Once a device has passed the Windows Hardware Quality Labs (WHQL) process, the manufacturer can use a "Certified for Windows" logo (or something very similar) in their advertising, and the device is allowed to be listed in the Windows HCL.

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

When Should You Use the Windows HCL?

Most of the time, the Windows Hardware Compatibility List serves as a handy reference when purchasing hardware for a computer you intend to install a newer version of Windows onto. You can usually assume that most PC hardware is compatible with an established version of Windows, but it's probably wise to double-check for compatibility with a version of Windows that hasn't been on the market very long.

The Windows HCL can also sometimes be a useful troubleshooting tool for certain STOP errors (Blue Screens of Death) and Device Manager error codes. While rare, it's possible that some errors that Windows reports are related to a particular piece of hardware could be due to a general incompatibility between Windows and that piece of hardware.

You could look for the troubled piece of hardware in the Windows HCL to see if it's listed as incompatible with your version of Windows. If so, you'd know that was the issue and could either replace the hardware with a make or model that is compatible, or contact the hardware maker for more information on updated device drivers or other plans for compatibility.

How to Use the Windows HCL

Visit the Windows Compatible Products List page to begin.

The first option has you select a group - either Device or System. Choosing Device lets you pick from products like video cards, audio devices, network cards, keyboards, monitors, webcams, printers & scanners, and security software. The System option is a broader selection that lets you choose between desktops, mobile devices, motherboards, tablets, and others.

After choosing the Device or System group, you need to select which version of Windows you're inquiring about. In the "Select an OS" section, choose between Windows 10, Windows 8, Windows 7, and Windows Vista.

Tip: Not sure which to choose? See What Version of Windows Do I Have? if you're not sure which operating system version you're running.

Once you've chosen a group and an operating system, pick the product you want to check compatibility with from the "Select a product type" option. It's here that you can choose between tablets, PCs, smart card readers, removable storage, hard drives, etc. These options depend on the group you chose in the "Select a group" section.

You can also search for the product in the search field, which is usually going to be much faster than browsing through all the pages.

For example, when looking for Windows 10 compatibility information on an NVIDIA GeForce GTX 780 video card, you can clearly see that it's compatible in both 32-bit and 64-bit versions of not only Windows 10 but also Windows 8 and Windows 7.

Selecting any of the products from the list will take you to a new page where you can see specific certification reports, proving that Microsoft has certified it for use in specific versions of Windows. The reports are even dated so you can when each product was certified.
