Windows Logo Kit

The Windows Logo Kit (WLK) contains everything needed to certify devices for Windows: Driver Test Manager (DTM), the required tests, and the documentation needed to set up DTM and execute the tests.

To qualify for the Windows Logo Program, your product must pass testing with the WLK:

• For a device logo: Pass tests that verify device reliability and performance.

• For a driver quality signature: Meet all criteria for drivers, as defined in logo program requirements.

• For a system logo: All devices and drivers in the system must have device logos or driver quality signatures, and the system must pass an additional series of tests.

Windows Logo Kit (WLK) 1.5 is now available for download on Microsoft Connect (log-in required). The primary purpose of this release is to provide content updates for Windows 7 and Windows Server 2008 R2 logo requirements in addition to older operating systems.
