Microsoft has released a public preview of Windows 12 featuring an AI-powered file management system that automatically organizes documents, photos, and downloads based on content analysis and user behavior patterns. The system learns from individual usage over time.

The preview also includes a redesigned taskbar, improved virtual desktop management, and deeper integration with Microsoft 365 Copilot. Performance benchmarks show the new OS running 15 percent faster on equivalent hardware compared to Windows 11.

Privacy advocates have raised concerns about the AI file analysis features, prompting Microsoft to emphasize that all processing occurs on-device and that users can disable the functionality entirely through system settings.
