Windows 11 introduces AI Copilot and enhanced file support in latest preview

Microsoft has released an early preview of Windows Copilot, a sidebar AI assistant for Windows 11 that can answer questions and perform system commands. The update also includes native support for RAR and 7-Zip files, an improved volume mixer UI, a new Settings homepage, and a suggestions feature for Snap Layouts. Windows Copilot is still in development and lacks full functionality, while the archive format support may have initial performance issues. These features are currently available for testing by Windows Insiders.
