Microsoft has released a major update to its Windows 11 operating system, which includes a chatbot called Copilot. Copilot, developed by Microsoft-backed OpenAI, uses generative artificial intelligence to create human-like text and perform actions in Windows. The new version of Windows 11 also includes PC-specific features such as app opening, dark mode switching, and screenshot guidance. Microsoft plans to sell the Microsoft 365 Copilot add-on for corporate workers. Windows 11 currently represents 24% of desktop PCs, according to StatCounter data, and Microsoft wants to keep it relevant as a foundation for its productivity apps and growth in the Azure cloud.
