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

Windows 11 continues its fast-paced evolution with the rollout of the much-anticipated 24H2 update, delivered under the preview banner of KB5055627. This update, now broadly available as Build 26100.3915, marks one of the most significant upgrades since Windows 11 first graced users’ PCs. It introduces powerful Copilot+ features, optimizations targeting everyday workflows, and a host of critical bug fixes designed to solidify the overall user experience. As Microsoft takes another big step towards AI-integrated computing, both Copilot+ PC owners and regular users will feel the impact—though in notably different ways.

The Rise of Copilot+ PCs and the Recall Revolution​

Central to this update is a suite of features reserved exclusively for the next-generation Copilot+ PCs. These devices integrate specialized Neural Processing Units (NPUs) and are designed to maximize the power of local AI. Topping the list is the new Recall function—an AI-powered experience that’s generating equal parts excitement and caution amongst Windows enthusiasts and privacy experts alike.

Recall: Your Personal Timeline, Powered by AI​

Recall is an ambitious feature: it continuously records snapshots of your desktop, enabling users to effortlessly search their PC history in plain, natural language. Did you forget where you saved that presentation or which website had the chart you need? Recall’s AI, powered by the system NPU, lets you simply ask and retrieve it.
Initially exclusive to Copilot+ PCs due to hardware requirements, Recall’s security model has faced scrutiny. Microsoft states that all snapshots are processed locally, encrypted, and protected by Windows Hello authentication. Furthermore, users can specify folders and apps that Recall should ignore, offering a degree of control to mitigate privacy risks. Independent analysis by privacy advocates such as The Verge and Tom’s Hardware echoes Microsoft’s emphasis on user control, but they recommend you regularly audit Recall’s settings—especially if handling sensitive information.
Still, the very nature of continuously capturing desktop activity has sparked debate. While Recall promises productivity benefits, it introduces risks related to unintentional data retention and potential misuse. Security researchers warn that, in the event of malware or unauthorized access, Recall’s historical records could become a target. As with any AI-driven feature, users are best served by an informed and cautious approach—balancing improved searchability with the imperative for digital privacy.

Click to Do: Instant Actions with AI​

Another major Copilot+ innovation is "Click to Do," accessed via the new Windows+Q shortcut. Drawing from AI context, this feature empowers users to interact directly with on-screen objects—such as erasing items in Photos or removing backgrounds in Paint—with just a click. It underscores Microsoft’s growing vision: turning Windows into an environment where advanced workflows are initiated with natural gestures and commands, rather than by navigating dense menus.

Smarter Search and Enhanced Local AI​

With Windows 11 24H2, semantic search capabilities receive a fundamental overhaul on Copilot+ PCs. Semantic indexing leverages the on-device NPU to deliver lightning-fast, offline searches across files, settings, and photos—moving away from the slower, and sometimes privacy-compromising, cloud queries of previous generations. Early feedback from insider previews points to meaningful improvements in speed and relevance, though these gains rest on having the appropriate NPU hardware.

Universal Improvements: File Explorer, Phone Link, Widgets, and More​

While Copilot+ PCs are front and center, Microsoft hasn’t forgotten the broad user base. The update ships with enhancements that benefit everyone.

File Explorer: Faster, Smarter, More Reliable​

ZIP file handling sees one of the most practical performance upgrades in recent memory. Extracting archives filled with hundreds—or thousands—of small files is now 5-10% faster, according to Microsoft’s own performance benchmarks. This might seem incremental, but for users handling large code repositories, asset packs, or photography projects, the improvement is tangible.
Other File Explorer refinements include more stable display of the address bar and better text rendering across dialog windows. Collectively, these changes continue a multi-release effort to restore File Explorer to the responsive, dependable utility it was before Windows 11’s initial teething troubles.

Phone Link Integration: Seamlessness Redefined​

Previously, Phone Link (formerly Your Phone) required users to launch a dedicated app to manage texts, calls, and notifications from their Android or iOS devices. Now, with KB5055627, deep integration sees Phone Link controls embedded directly into the Start Menu. You can review recent messages, access photos, or see incoming calls—streamlining cross-device workflows and making Windows a true command center for the digital life.

Widgets and Voice Output: Personalized Interaction​

Widgets also enjoy greater flexibility, with more predictable display behavior and better performance. Meanwhile, users now benefit from the ability to review spoken output generated by accessibility features, making it easier to catch details missed due to distractions or interruptions—a subtle but vital change for inclusivity.

Under the Hood: Critical Fixes and Enhanced Stability​

No Windows update is complete without the obligatory bug fixes, but KB5055627’s patch list is particularly impactful.

Blue Screen of Death (BSOD) and Secure Kernel Error​

Following April’s patch day, a subset of Windows 11 users encountered persistent BSODs tied to the error code secure_kernel_error (0x18b). This update claims to resolve that thorny issue, restoring system reliability for those affected. Multiple user reports across Microsoft forums and Reddit confirm that post-installation, these crashes are largely a thing of the past.

Network and Connectivity Woes Addressed​

Another widespread complaint involved loss of network connectivity on waking the system from sleep. Microsoft’s engineers have traced and remediated these power management glitches, resulting in more consistent wireless performance—particularly vital on modern ultrabooks and always-on tablets.

Taskbar and Window Management Refinements​

Persistent underlines beneath app icons on the taskbar—left over after closing apps—have also met their end in this release. The update further fixes edge cases where Windows Hello authentication failed after a system reset, addressing an issue that had left some devices inaccessible or forced into convoluted recovery scenarios.

Touch and Accessibility: Small Changes, Big Impact​

Gestural support in the Start Menu for touch-first devices has been fine-tuned, enabling smoother and more predictable swipes and taps. Meanwhile, desktop app links have shed their colored backgrounds in favor of transparency, harmonizing with Windows 11’s Fluent Design System for a cleaner look.

Smarter Updates: Estimated Offline Time​

Perhaps one of the more user-requested features is the explicit display of estimated offline time required during update installation. Both in Windows Update settings and in the Start Menu, users now see a realistic forecast of the downtime required—helping to avoid unpleasant surprises when updates occur during critical work windows.

Installation and Rollout: What to Expect​

Obtaining KB5055627 is straightforward: it’s delivered via the standard Windows Update mechanism in Settings, or, for those who prefer manual download, available from the Microsoft Update Catalog. Microsoft is transparent that not all features launch for all users immediately—many are subject to phased rollouts enabled by controlled feature flags. This can result in some users seeing new capabilities before others, even after receipt of the update.
On Microsoft’s official support page for this release, administrators and advanced users will find detailed breakdowns of what’s included, what’s changed, and what’s pending further investigation.
