Microsoft's introduction of Copilot in Windows 11 marks a significant leap in AI-powered productivity, offering users two distinct flavors: the original system-wide Copilot and the specialized Microsoft 365 Copilot. These intelligent assistants promise to revolutionize how we interact with our PCs, but understanding their differences is key to maximizing their potential.
