Windows 11 June Update Introduces Low Latency Profile and Other Performance Features
Microsoft has released the Windows 11 June cumulative update (KB5094126) for versions 24H2 and 25H2, introducing a Low Latency Profile feature that briefly boosts CPU clock speed to accelerate app launches and core shell elements like the Start Menu and Action Center. The update also speeds up search results, adds shared Bluetooth audio support, enables multi-app camera access, and patches 206 security vulnerabilities including a critical kernel-level remote code execution flaw rated 9.8 out of 10. The release marks a significant performance and security milestone for Windows 11, though the Low Latency Profile is rolling out gradually and may not activate immediately on all eligible devices.
Microsoft's June Patch Tuesday update for Windows 11, identified as KB5094126 (OS Builds 26200.8655 for 25H2 and 26100.8655 for 24H2), delivers one of the heavier update packages in recent memory. The headline feature is the Low Latency Profile (LLP), which instructs the CPU to jump to maximum clock speed for one to three seconds when a user opens an app or system shell element such as the Start Menu, Search, or Action Center, then returns to normal — a technique already common in macOS and Linux. The improvement is expected to be most noticeable on older or less powerful hardware, and users can verify whether LLP is active on their system by monitoring real-time CPU frequency spikes using tools like HWiNFO64 or HWMonitor, since Windows itself provides no built-in indicator. Additional features include Shared Audio for broadcasting sound to two Bluetooth LE devices simultaneously, a search improvement that surfaces results after just two characters are typed, multi-app camera support, NPU monitoring in Task Manager, and the ability to set a custom user folder name during setup. On the security side, Microsoft patched 206 vulnerabilities, with one kernel-level remote code execution flaw (CVE-2026-45657) carrying a near-maximum threat score of 9.8, and the company noted that AI tools are accelerating vulnerability discovery on both sides of the security divide. Because LLP is being deployed as a controlled rollout, users who install the update may not receive the feature immediately.
What's missing
The sources do not specify how long the controlled rollout of Low Latency Profile is expected to take before reaching all eligible devices, nor do they clarify whether the feature will eventually be user-toggleable. The full list of the 206 patched CVEs and their individual severity ratings is not detailed across any of the sources.
How coverage differed
TechRadar and PCWorld focused primarily on the Low Latency Profile as a consumer-facing performance improvement, with cautious framing around its gradual rollout. Engadget adopted a more sardonic tone — headlining that 'Windows 11 sucks slightly less now' — and gave comparatively more weight to the 206 security patches and the critical CVE, framing the update as a broader relief package for a struggling operating system.

The discounts make previously premium-priced devices more accessible to budget-conscious consumers.
Anthropic Disables Fable 5 and Mythos 5 AI Models Globally After US Government Export Control Order
Anthropic has suspended all public access to its two most advanced AI models, Fable 5 and Mythos 5, after the US Commerce Department issued an export control directive ordering the company to block foreign nationals from accessing them on national security grounds. The order came just three days after Fable 5's public launch and reportedly stems from government concerns about a potential jailbreak that could enable the models to assist with cyberattacks, though Anthropic says it received only verbal evidence of a narrow, non-universal vulnerability. The shutdown affects all customers globally — including enterprise users and Anthropic employees — and marks a significant escalation of US efforts to restrict foreign access to advanced AI models themselves, rather than just the chips that power them.
