At the heart of the 24H2 update is the introduction of Recall (preview), a transformative AI-driven feature designed to tackle a perennial computing frustration: finding previously viewed content. Recall acts as a hyper-intelligent, secure assistant, capturing snapshots of user activity across applications, websites, images, and documents. When users need to retrace their digital steps, Recall leverages local AI processing—courtesy of high-efficiency NPUs boosting 40+ trillion operations per second (TOPS), according to Microsoft’s latest design targets—to deliver near-instant search and recall.Opt-in Security and Control: It’s critical to note that Recall’s snapshotting is opt-in. Users must actively enroll via Windows Hello and can fine-tune which activities or apps are captured—or choose to pause or delete snapshots at any time. Security is enforced through Windows Hello authentication, ensuring only the authorized user can access their digital timeline. Microsoft claims that Recall’s data never leaves the device unless explicitly shared, aligning with contemporary privacy expectations. However, privacy advocates and enterprise IT departments will likely scrutinize the long-term retention of such granular personal data, even if encrypted and isolated on-device.
Click to Do (Preview): In-Context Actions, Accelerated
Click to Do expands the on-screen interaction paradigm, enabling users to immediately launch contextually relevant actions based on what they see. Select an image and you could quickly erase objects in the Photos app, or remove a background in Paint, all triggered directly from an overlay invoked with Windows key + mouse click or Windows key + Q. By merging the Snipping Tool’s visual selection smarts with AI-driven workflows, Microsoft is focusing squarely on reducing the friction of routine tasks.Exclusive to Snapdragon-powered Copilot+ PCs are intelligent text actions—highlight and extract actionable snippets, such as copying, searching, or translating directly from a visual selection. “Click to Do” is designed for extensibility and manageability: IT admins can govern its behavior using new management policies, which may prove essential for organizations with stringent workflow or security requirements.
Enhanced Windows Search: Semantics Meet Speed
One of the most understated yet impactful upgrades in this update is the overhaul of Windows Search—especially on Copilot+ systems. The integration of on-device semantic search models means users no longer need to remember precise filenames or cryptic search syntax. Whether searching for settings (“change my theme”) or files (“presentation about Q2 earnings”), improved natural language understanding untethers users from the rigidity of traditional keyword search. The AI models driving this enhancement run locally, ensuring snappy responsiveness even when offline.Additionally, search now unifies results from both local storage and the cloud (e.g., personal OneDrive accounts) for a seamless hybrid experience. Users can craft queries with their own words—such as “summer picnics”—and receive results matching photo content or document text, blending personal productivity improvements with advances in AI compute power.
Phone Link: Deeper Cross-Device Integration
Phone Link, Microsoft’s cross-device bridge between PCs and mobile devices, now offers even tighter integration directly from the Start menu. Quickly make phone calls, send SMS messages, browse photos, or transfer content, all without switching devices.
