Windows Logo Kit
From Wikipedia, the free encyclopedia
The Windows Logo Kit (WLK) is a test automation framework provided by Microsoft to certify devices for Windows.
It provides automated scheduling and execution of the driver tests that hardware vendors are required to pass in order to qualify to use the Microsoft Designed for Windows Logo. Besides, it also enables users to automate driver tests which they have created themselves. These tests can be mixed and matched with the Logo tests provided by Microsoft to create a custom test pass enabling organizations to use the DTM to validate drivers in any way they see fit.
[edit] History of Windows Logo Kit
During the Windows 2000, XP, 2003 timeframe there was an old tool Hardware Compatibility Test (HCT) to certify devices. When Windows Vista was released the tool was replaced by Driver Test Manager (DTM) which can certify drivers for all then-supported platforms. At that time DTM was part of Windows Driver Kit (WDK). Later DTM was separated from WDK and changed to its current name, Windows Logo Kit.
