Microsoft offers the Windows Logo Program to help customers identify systems and peripherals that meet a baseline definition of platform features and quality goals that ensure a good Windows experience for the end user. The Windows Logo is not intended to communicate the specific technical capabilities of any particular system.
Products that earn the Windows Logo have been tested to ensure that they meet Microsoft standards for compatibility on the Windows operating systems designated on the logo. System and peripheral manufacturers can license the Windows Logo for use on product packaging, advertising, collateral, and other marketing materials for all systems and components that pass compliance testing.
Products that carry the Windows Logo for hardware include these characteristics:
All components install and uninstall properly and do not interfere with other system components.
Each component interoperates well with other system components.
All components function normally after the operating system is upgraded to Windows XP/Windows 2000 or any later version of the operating systems for which the system or component carries the logo.
These characteristics yield these benefits for manufacturers:
Increased customer satisfaction
Lower support costs
Fewer product returns
Windows Logo Program requirements are intended to support a good user experience with the Windows operating system. In this context, a "good user experience" means a reliable, consistent experience with system hardware, firmware, drivers, and related software components. In particular:
The user is assured that a product that has the Windows Logo will be stable when running under the operating systems listed on the Windows Logo carried by that product or listed in the Hardware Compatibility List.
The user can easily begin and complete component installation or removal. Installing and using a component that has the Windows Logo will not cause the system to stop working, or otherwise disrupt Windows or other Logo’d software running on the computer.
The user’s overall experience with the computer system and the operating system is the same or better after upgrading to a new Windows operating system.
IMPORTANT: The presence of the Windows Logo on a hardware product does not mean that Microsoft endorses or certifies a product. The Windows Logo is not a quality assurance seal. Microsoft does not test the quality of each hardware product or ensure that it is bug free.
Microsoft licenses different versions of the "Designed for Windows" logo for specific operating systems on servers, desktop PCs, mobile PCs, and their components, as described in this section. The Windows Logo explicitly identifies the versions of the operating system for which the product passed compliance testing. Testing is conducted by Windows Hardware Quality Labs, as described in Chapter 4 of this guide.
The specific Windows Logo for the system or device indicates which operating system versions the manufacturer supports for the system or device. The current, comprehensive listing of available logos is provided at http://www.microsoft.com/winlogo/hardware/.
Windows Logo Program requirements vary for different classes of products (for example, server, desktop, or mobile) and for different market segments (for example, enterprise server, commercial desktop, or consumer desktop). Where system design guides and other references refer to consumer and business PC system types, the following meanings apply for the Windows Logo Program:
Business PC (also referred to as office PC or commercial PC): The system comes with Windows XP Professional or Windows 2000 Professional preinstalled.
Consumer PC: The system comes with Windows XP Home Edition or Windows 98/Me preinstalled.
Note: Test logs for Windows XP are required for all logos.
Dates for specific Windows Logo Program requirements are defined on the web at http://www.microsoft.com/winlogo/hardware/.
Windows Logo Program requirements become effective in these ways:
Operating System Support. Some requirements become part of the Windows Logo Program based on features in the operating system that the manufacturer preinstalls on the system.
For example, OnNow power management and multiple monitor support became Windows Logo Program requirements a few years ago when new support was introduced in Windows operating systems. These types of requirements depend on which operating system is preinstalled on the system. For example, in past years, a system with Windows NT 4.0 preinstalled was not required to fully support Windows Driver Model (WDM) requirements.
Another example is support for legacy-free designs, first introduced in the Windows 2000 and Windows Me operating systems. For this example, the OEM can choose whether to build legacy-free designs; however, if implemented, the system must meet the specific Windows Logo Program requirements for such systems.
Industry Advances. Some technical requirements are market driven and take time to become broadly adopted because of cost or development time.
Such technical advances are introduced as proposed guidelines in the Design Guides (jointly authored by Microsoft Corporation and Intel Corporation). Based on industry feedback about time-to-market issues identified during the Design Guide review cycle, these technical advances become part of the Windows Logo Program requirements on a timetable that the majority of the industry has agreed is technically possible and cost effective.
Some technical advances proposed in the PC and Server Design Guides include support for features in yet-to-be-released versions of Windows operating systems. For example, Advanced Configuration and Power Interface (ACPI) support was required in the Design Guides before ACPI-capable versions of Windows were available.
In special cases such as ACPI, the Logo Program requires design changes in advance of the availability of the operating system in order to ensure value in the installed base of PCs for future operating system upgrades. Actual requirements and effective dates under the Windows Logo Program are based on consensus from industry review to ensure that the platform advances can be made at an acceptable cost and in a reasonable time frame.
To plan for Windows Logo requirements based on new operating system features, participate in Microsoft design reviews and beta testing programs. For more information about how to plan and design systems that ensure operating system compatibility and that comply with Windows Logo Program requirements, see Appendix C, "Designing for Success."
