Microsoft is redefining what an operating system can be. With the rollout of Windows 11 version 25H2, the company is introducing a new era where your PC doesn’t just respond — it understands, plans, and acts. This evolution marks Windows 11’s transition into an agentic, AI-native operating system, built around Copilot, Microsoft’s intelligent system assistant.
As Windows 10 moves out of mainstream support, Windows 11 becomes the foundation for the next generation of AI PCs, where interacting with your computer naturally — through voice, context, and intent — becomes the default experience.
Copilot: The Intelligence Layer of Windows
The new Copilot experience goes far beyond simple chat interactions. It now functions as a true system-level AI agent, capable of understanding your goals, taking contextual actions, and performing tasks across applications, settings, and files — all within your control.
What’s New in Windows 11 25H2 and Insider Builds
1. Direct Control of System Settings
Copilot can now open and modify Windows settings directly. Whether you want to turn on Bluetooth, switch power modes, or enable accessibility options, a simple voice or text command gets it done.
2. Settings AI Agent (Powered by Mu)
A new on-device AI model called Mu powers a smarter Settings experience. It understands natural language requests and can execute multi-step configuration tasks for you — like optimizing performance or changing network settings in one go.
3. File Explorer AI Actions
File management gets an AI boost. File Explorer now offers quick actions such as Summarize, Blur Background, Erase Objects, and Remove Background, all powered by integrated Copilot intelligence and creative tools from Paint and Photos.
4. Microsoft 365 Integration
Business users can now access People Cards directly from File Explorer and use Summarize on OneDrive and SharePoint files through the right-click menu — making collaboration and document insight seamless.
5. Gaming Copilot (Beta)
Gamers now have a personal gaming assistant inside the Xbox Game Bar. The new Gaming Copilot can provide in-game strategy tips, achievement information, or performance suggestions using natural voice commands.
New Experiences: Widgets, Voice, and Discover Feed
The Widgets board has been reimagined with a Copilot-curated Discover feed, offering personalized stories, summaries, and videos. Users can also customize multiple dashboards and see widget previews on the lock screen.
Voice access has been significantly upgraded too. Windows now understands natural voice commands like “Can you open Edge?” instead of rigid phrases. This improvement enhances both accessibility and convenience for all users.
Expanding AI Capabilities Across Windows
Creative Tools and File Explorer
Microsoft continues integrating AI into its creative suite:
- Photos: Generative AI tools let you blur or erase unwanted objects.
- Paint: Now includes one-click background removal and support for the new
.paintfile format. - Snipping Tool: Allows quick markups before saving screenshots.
- Notepad: Gains local AI functions like summarizing and rewriting text — no cloud or subscription needed on Copilot+ PCs.
Recall and Click-to-Do: Smarter Daily Assistance
Recall (Preview) introduces a personalized timeline that helps you pick up where you left off — surfacing recent snapshots, apps, and frequently used websites.
Meanwhile, Click to Do brings context-aware actions powered by Microsoft’s Phi Silica small language model. These smart action tags summarize what you’re viewing and suggest the next steps instantly.
Developer and System-Level Enhancements
Windows 11 25H2 includes deep system updates to support the AI era:
- Advanced Settings Redesign: Formerly “For Developers,” it now integrates Git details in File Explorer and is open source on GitHub.
- Windows ML (General Availability): Enables on-device AI inferencing across CPU, GPU, and NPU for faster, private computation.
- Rust in the Kernel: Parts of the Windows kernel are rewritten in Rust, improving memory safety and reducing vulnerabilities.
- Wi-Fi 7 Support: Provides faster and more stable network connections, including for enterprise use.
- Task Manager Improvements: Adds a “CPU Utility” column for clearer performance insights.
Reinforced Security and Privacy
Microsoft is tightening security as AI takes a larger role in system operations:
- Windows Hello visual refresh automatically prioritizes your best credential.
- Passkey Manager integration brings compatibility with tools like 1Password and Dashlane.
- Windows Resiliency Initiative improves phishing and malware protection.
- App Control for Business allows IT administrators to approve only trusted apps through Intune-managed installers.
All agentic features — including Copilot Actions — remain opt-in, ensuring user transparency and control.

With every release, Windows moves closer to being an AI-powered platform that understands intent, manages context, and executes actions seamlessly — transforming the PC into a true digital partner.
The age of the agentic PC has officially begun.
