Windows 7 Portable Devices and the Windows Logo Program
With the release of Windows 7 we are seeing a great deal of maturity of the Windows Portable Device (WPD) Platform. The WPD Platform includes the WPD APIs with WPD Automation and native Device Services, the Media Transfer Protocol (MTP) class drivers with MTP over USB, MTP over IP, and MTP over Bluetooth. For more information on what was new for Windows 7, see our New Features for Windows 7 post. Due largely to the native support in Windows and our high level of engagement with industry partners we were able to put together a new comprehensive Logo program for Portable Devices that work well with Windows.
This blog post covers the following topics:
- What is the Windows Logo Program for Hardware?
- Supported Portable Device Logo Programs
- Prepared Requirement Reports
- Windows Logo Kit
- Additional Information on the Windows Logo Program for Hardware
- Development Tools and Support
What is the Windows Logo Program for Hardware?
The Windows Logo Program is designed to address the current and future market needs of customers using the Windows platform. The Windows logo signifies the compatibility and reliability of systems and devices with the Windows operating system. It gives customers confidence that your product is thoroughly tested with Microsoft-provided tools and ensures a good user experience.
The Windows Logo Program helps partners to innovate and bring a premium experience to market, thereby improving their ability to increase market share. The program strives to continuously improve its processes, responsiveness, and partner satisfaction.
Supported Portable Device Logo Programs
There are currently 3 logo categories that are accepting submissions for Portable Devices, they are:
Digital Still Camera- This program supports logo for Windows 7 and Windows Vista
Portable Media Player- This program supports logo for Windows 7 and Windows Vista. The PlaysForSure program was retired at the end of August 2009.
Cellular Handset (Phone) - This program supports logo for Windows 7, Windows Vista, and Windows XP.The PlaysForSure program was retired at the end of August 2009.
With the release of the Windows Logo Kit (WLK) 1.5, which is due to release at the end of November 2009, we will see one additional category:
Other Portable Devices - This program supports logo for Windows 7.
This new category is being made available as an option for hardware manufacturers that support the core set of MTP Revision 1.0 operations, device properties, and object formats. Passing this logo program provides validation that the device has implemented the MTP protocol correctly, so that the device will work as expected with the MTP class driver in Windows 7.
The following table provides a breakdown of requirements for each of these 4 categories. The ‘R' in the table implies that the operation,property, or object format is required. If the field is blank the requirement is optional.

Prepared Requirement Reports
The Windows Logo Program for Hardware creates a list of requirements that the validation tests are based on. During the hardware design phase it is critical that manufacturers that are going to be involved with the logo process review the logo requirements that are applicable to a target OS,such as Windows 7. Although the majority of requirements that are outlined for Portable Devices are based on industry standards and specifications or white papers published by Microsoft, there are some requirements that may not be apparent until you attempt to run through the WLK and come across a failure that you do not expect. For example, we have portable device specific behavior requirements defined but there are also fundamental requirements that apply to all devices for Windows. There are also requirements that apply to all USB devices, one such requirement is support for USB serial numbers for all portable USB devices. Additional requirements can be reviewed by downloading the Prepared Requirements Reports which are organized by specific hardware technologies.
Windows Logo Kit
The Windows Logo Kit (WLK) is used to validate the requirements defined for the logo program. This kit can also be used for product development. We encourage its use during the product development cycle of hardware in order to ensure device compliance with both Windows and industry standards. The kit includes several tests designed to validate device implementation and behavior at multiple levels. There are tests for USB compliance, MTP compliance, and WPD platform compliance that also cover device services validation.
Thecore tests provided for portable devices are:
- MTP Compliance Tests
- WPD Compliance Tests
- WMDM Compliance Tests
- WMDM Sync Test
For detailed description of these tests, please go to the WLK help documentation.
There is a significant amount of information available about the WLK, including user guides and video tutorials. For more information about the WLK see: https://www.microsoft.com/whdc/winlogo/WLK/default.mspx
The kit is free to download and use.
Additional Information on the Windows Logo Program for Hardware
There is a wealth of additional information that has been made available for this program. Here are some of the key helpful links that will help you navigate the logo program.

We strongly encourage anyone that is going to participate in the logo program to review the Windows Logo Program Webcasts as well. These are a series of videos that can be viewed on demand that covers logo planning, testing, development, and how to submit logo packages using the qualification page at https://winqual.microsoft.com.
Development Tools and Support
There are several development resources available for portable device manufacturers. Probably the best source for this information was put together and released as a WPD Team Blog back in September, refer to Windows7 Portable Device Development Kits for details. That blog post covered the following development resources:
- Windows 7 Portable Device Enabling Kit for MTP
- Windows Portable Devices SDK
- Windows Portable Devices Driver Kit
- Windows Media Device Manager SDK
- Microsoft Device Experience Development Kit
- Windows Logo Kit
