The Office UI licensing program, originally launched in November 2006, has been retired. When the program was introduced in 2006, developer frameworks for the Office Ribbon did not exist. Microsoft tools and technologies now provide developers a variety of options, code, and developer frameworks for implementing the Office Ribbon UI in Windows applications.
If you are a developer that already signed up for the Office UI licensing program and accepted the licensing terms, then you will continue to have rights under that license to implement the Office UI per the terms of that license. There are no changes at all for existing Office UI program licensees.
If you are not already licensed to use the Office UI under the retired program, you can use any of the Microsoft tools and frameworks to implement the Ribbon UI in your current or future Windows applications. The license terms associated with the Microsoft developer framework will apply. For example, current developer frameworks that are licensed for creating a Ribbon UI include:
If you are not already licensed under the Office UI licensing program, and you do not want to use any of the Microsoft tools and technologies, Microsoft no longer has a separate Office Ribbon UI licensing program.
