Microsoft is preparing to integrate its AI assistant, Copilot, directly into the core of the Windows operating system to help users perform various productivity tasks. This approach, which Microsoft refers to as "hybrid intelligence," combines AI models that run locally on the user's device with more powerful models hosted in the cloud. To ensure user data remains secure, these local AI agents will operate within isolated environments called Microsoft Execution Containers, which have strict permissions during execution. While this local processing aims to improve privacy, its effects on battery life and system performance are still unclear. During a major event on October 7, 2026, Microsoft unveiled a significant update to Copilot, allowing it to access users' local files and perform actions across the entire Windows operating system. This update is part of a broader project to turn Windows into an "agent platform," where Copilot would not just chat with users but actively manage the computer. This new feature was initially tested with Windows Insider users in 2025 through a preview called Copilot Actions. Microsoft’s advantage in this effort lies in its direct control of the Windows operating system, which is used by the majority of personal computers worldwide. Unlike companies such as OpenAI and Anthropic, which provide AI models through third-party apps or platforms, Microsoft is embedding its AI assistant directly into its operating system. This native integration could give Microsoft a competitive edge as demand grows for AI tools that can perform complex tasks independently. However, the success of this update will depend on users' willingness to grant Copilot access to their files and system settings, especially given that the number of users who pay for Microsoft 365 Copilot remains relatively low. Despite the potential benefits, Copilot has faced criticism from users, who are concerned about security and privacy. Microsoft has addressed these concerns by implementing multiple layers of control, including requiring user consent to activate features, limiting access to specific folders, and ensuring that AI agents run under separate accounts. In a demonstration, Copilot was shown accessing emails, organizing documents, and preparing a draft email with attachments. These capabilities go beyond basic document management and include features like changing system settings or sending messages. The deployment of Copilot will initially begin with GitHub Copilot before gradually expanding to the general Copilot application. Microsoft also introduced the Surface Laptop Ultra, a new device equipped with Nvidia chips designed for AI processing, positioning it as a competitor to Apple's Mac Mini. However, some users are frustrated with Microsoft’s push to integrate Copilot into various applications and hardware, including a dedicated button in some devices that has been shown to reduce productivity. The term "Microslop" has emerged online to describe the often mediocre content generated by AI tools, including Copilot. Microsoft has had to reduce the visibility of the Copilot brand in its messaging apps due to this perception. An ex-vice president of Microsoft previously noted that only 3.3% of Microsoft 365 users pay for Copilot, and its market share remains low. With GitHub Copilot also facing competition from tools like Cursor and Claude Code, which are growing faster, Microsoft's strategy of bundling Copilot with its services may not be enough to change user behavior.
