Although PC 99 System Design Guide contains a complete set of PC and peripheral design guidelines, hardware designers can expect that Microsoft will continue to respond to industry comments about specific requirements and the planned dates for Windows Logo Program compliance testing.

Important: If you implement a recommended feature in a system or component that you submit for Windows Logo Program compliance testing, you must meet the implementation guidelines defined in PC 99 System Design Guide. The PC 99 recommendations are based on the support in Windows 32-bit operating systems, which is why a recommended feature must meet the guidelines for Windows Logo compliance.
