The new Windows HLK for Windows 10 is an evolution of the Windows Logo Kit (WLK) and the Windows Hardware Certification Kit (HCK). It is designed to help your company deliver systems, software, and hardware products that are compatible with Windows and run reliably on Windows 10 for desktop editions (Home, Pro, and Enterprise), and the next version of Windows Server. Like previous versions, the tests in Windows HLK for Windows 10 enable you to take advantage of the Windows Hardware Compatibility Program (formerly the Hardware Certification Program). After passing certain tests, the program allows you to use the Windows logo as part of your marketing.
