Microsoft is retiring the iconic "Office" brand and rebranding its popular products like Word, Excel, and PowerPoint under the "Copilot" name, as part of its shift toward an AI-driven future. This change, announced in 2023, reflects the company’s heavy investment in AI, particularly through its partnership with Open AI. The rebrand to Copilot aligns with Microsoft's broader AI strategy and its efforts to create a unified AI identity across its products. While the transition may confuse some users, especially those familiar with the Office brand, it highlights Microsoft's commitment to integrating AI features into tools like Excel and Word. The new branding is already being introduced on Windows 11 for select users.
