Microsoft updated three passages in its Responsible AI Principles on April 19, 2026. The first change revised the opening tagline from 'Build your business with trustworthy AI' to 'Accelerate business growth with trustworthy AI' and expanded the supporting description from a single sentence about safe practices to a more detailed statement about accelerating adoption and reducing risk. The second change replaced a reference to 'Get the e-book' with 'Watch the webinar' in a resources section. The third change rephrased guidance about Copilot security from 'When you're using Copilots at work' to 'When using Copilot at work,' a minor grammatical adjustment. These are primarily marketing and messaging updates with no material change to underlying responsible AI commitments or consumer obligations.
These changes are primarily editorial and marketing updates to Microsoft's Responsible AI Principles. The revised language emphasizes business value and risk reduction rather than introducing new restrictions or permissions. The shift from 'e-book' to 'webinar' and the grammatical adjustment to Copilot guidance do not alter what users can do or what data the platform collects. The updated terms make no substantive change to user rights, data handling, or security obligations.
The updated language strengthens emphasis on business value and operational risk management in Microsoft's responsible AI messaging, but does not modify underlying policies, permissions, or data handling practices. Organizations evaluating Microsoft's responsible AI commitments should note the revised framing focuses on acceleration and risk reduction alongside trustworthiness.
Marketing language shifted from 'Build your business with trustworthy AI' to 'Accelerate business growth with trustworthy AI' with expanded supporting description.
Resource guidance updated to reference a webinar instead of an e-book.
Security guidance rephrased from 'When you're using Copilots at work' to 'When using Copilot at work' without substantive change to the requirement itself.
