Windows 11 24H2 Update: AI-Powered Features, Recall, and Performance Improvements

Microsoft continues to evolve its Windows 11 operating system at a rapid pace with the rollout of the 24H2 update, officially distributed under the preview cumulative update KB5055627. This release, available as Build 26100.3, marks a significant step toward embedding artificial intelligence (AI) deeply into daily computing experiences, alongside several system stability enhancements and usability improvements. Designed primarily for advanced users and IT professionals eager to preview upcoming capabilities ahead of broader deployment, KB5055627 exemplifies the future Microsoft envisions for Windows: a smart, intuitive, and productivity-focused platform.

Context and Background: Windows 11’s Evolution into an AI-Centric OS

Windows 11 24H2 is more than a traditional update patch. Its ambition extends beyond incremental bug fixes and performance tuning toward a fundamental rethinking of how users interact with their PCs through AI. The update is part of Microsoft's monthly non-security preview cadence, allowing users to test new functionalities that are set to be fully integrated in upcoming major updates.

Central to 24H2 is Microsoft's strategy around "Copilot+ PCs" — devices equipped with dedicated neural processing units (NPUs) capable of running on-device AI models without reliance on cloud connectivity. This hardware-software synergy enables advanced AI-powered features that personalize and optimize workflows, making task automation and content retrieval more intuitive.

Key AI-Powered Features in KB5055627

1. Recall (Preview)

One flagship feature is Recall, a revolutionary tool that transforms Windows 11 into an intelligent memory augmented system. Recall automatically captures snapshots of user activities, including apps in use, documents opened, websites visited, and presentations shown. These snapshots—essentially visual and contextual breadcrumbs—are stored locally and can be retrieved through natural language queries.

Users can approach Recall as a smart digital assistant for their digital history, enabling them to find past work without recalling exact file names or locations. Privacy is a cornerstone of this feature: snapshotting is opt-in, data access requires Windows Hello authentication, and users have transparent controls to pause or delete data snapshots. Microsoft plans a gradual rollout of Recall throughout 2025, with particular care in markets such as the European Economic Area where privacy requirements are stringent.

2. Click to Do (Preview)

Click to Do introduces AI-powered inline actions on selected images and text. This feature allows rapid contextual interactions, such as erasing objects from images or removing backgrounds using Windows built-in apps like Photos and Paint. Text selections can be summarized, rewritten in various tones, or otherwise manipulated using the on-device Phi Silica language model, enhancing creativity and communication efficiency. The feature supports flexible activation through keyboard shortcuts, snipping tool menus, or taskbar search, and offers enriched capabilities on Snapdragon-based Copilot+ PCs.

3. Semantic Search Upgrade

Windows Search has received a significant AI upgrade, particularly on Copilot+ PCs. It now supports semantic indexing empowered by local AI, enabling more natural and context-aware search queries. For instance, querying "summer picnics" retrieves relevant photos from both local storage and OneDrive cloud storage, usable even offline. This intelligent search reduces friction in finding files, photos, or settings, offering a glimpse into future smart desktop experiences.

Broader Update Enhancements

Beyond AI, KB5055627 brings crucial fixes and general enhancements, targeting long-standing reliability issues and usability improvements:

  • Bug Fixes: Critical fixes address the troubling 0x18B SECUREKERNELERROR blue screen triggered by prior updates, intermittent network issues related to DHCP client problems after device sleep, and problematic Windows Hello facial recognition or PIN login failures on some security-enabled devices.
  • File Explorer Improvements: File Explorer gains features like creating TAR and 7z archives natively with enhanced visibility for common commands and better support for Android file syncing, improving cross-device productivity.
  • Phone Link Integration: The update introduces Phone Link capabilities integrated directly into the Start menu, streamlining cross-device workflows including calls, SMS, and photo sharing.
  • Accessibility Enhancements: New Narrator speech recap capabilities help users with assistive technologies follow spoken content more effectively.
  • Performance Tuning: Optimizations target AMD Ryzen and Intel processors, including support for new generation chips, promising smoother multitasking and faster operations.
  • User Experience: Estimated update offline times are now displayed during Windows Update installations, a long-requested feature enhancing transparency and reducing downtime uncertainty.

Privacy, Security, and IT Management Considerations

While AI-powered features promise significant productivity gains, they also introduce nuanced privacy and compliance challenges, especially in enterprise environments. Since Recall continuously captures activity snapshots, organizations must carefully manage user opt-in policies and educate users to prevent inadvertent exposure of sensitive data.

Microsoft embeds strict privacy controls: features are opt-in, data is stored locally, and access requires biometric or PIN authentication. From an IT perspective, this update offers policy enforcement capabilities to govern these AI functions in managed devices.

Security-wise, even though KB5055627 excludes new security patches as a preview, it continues to improve Windows' overall security posture by fixing vulnerabilities around kernel stability and network components.

Known Issues and Deployment Guidance

As with many preview releases, KB5055627 includes some known issues:

  • Certain Citrix components block the update installation, requiring temporary workarounds per Citrix documentation.
  • Roblox users on Windows ARM devices may face installation limitations from the Microsoft Store, necessitating direct downloads from the Roblox website.

Given the hardware demands for Copilot+ AI features, only devices with specific NPUs (including Snapdragon, Intel Lunar Lake, and AMD Ryzen AI 300 platforms) can fully leverage the update's AI functions. This hardware requirement creates a divide in the Windows user base between AI-enabled PCs and traditional systems.

Microsoft recommends backup before installation and cautious rollout, especially in enterprise contexts, given the update's complexity and evolving nature.

Implications and Future Outlook

KB5055627 anticipates a future where Windows transcends traditional operating systems, evolving into a proactive personal assistant and productivity partner. The integration of AI tools like Recall and Click to Do signals a shift toward a context-aware OS capable of anticipating user needs and simplifying complex tasks.

For end users, this promises enhanced efficiency in searching, managing files, and multitasking. For IT professionals, this introduces new dimensions to workflow management and user privacy enforcement. The update marks a clear milestone in Microsoft's vision to blend AI tightly with system core, driving Windows 11 into a responsive, intelligent future.

As AI technologies mature and more users adopt Copilot+ hardware, Microsoft’s Windows ecosystem will likely see further deep integration of AI, improved cross-device synergy, and smarter interfaces that anticipate and act on user intent.

Conclusion

Windows 11 24H2 through preview update KB5055627 is a landmark release that brings a rich suite of AI-powered productivity enhancements, significant bug fixes, and system optimizations. Its AI-first features — most notably Recall and Click to Do — highlight Microsoft’s commitment to transforming Windows into a learning, adaptive platform designed to empower users in their everyday tasks. At the same time, the update carefully balances innovation with vital privacy safeguards and system reliability improvements.

While currently targeted at advanced users and organizations ready to explore next-generation features, KB5055627 lays a strong foundation for the future of Windows — one that is smarter, more connected, and ultimately more helpful in navigating the expanding digital landscape.
