Windows 11 Sucks Slightly Less Now, Thanks To A June Update

The June update for Windows 11, identified as KB5094126 (OS Builds 26200.8655 and 26100.8655), introduces significant enhancements and numerous bug fixes and security patches. A key feature is a low-latency profile that improves responsiveness of core system elements like the Start Menu and Search by allowing the CPU to quickly reach maximum clock speed upon user interaction. This update also refines the Start Menu, improves app launch speeds, and addresses longstanding issues such as faster downloads from the Windows Store and optimized Windows Search results. New features include multi-app camera support, Shared Audio functionality for streaming to multiple Bluetooth devices, and the ability to personalize user folder names during installation. Additionally, the update resolves 206 security vulnerabilities, including a critical kernel-level remote code execution vulnerability (CVE-2026-45657) with a threat score of 9.8.

Windows’ June update finally makes your sluggish PC feel snappier

Microsoft has rolled out the "Low Latency Profile" feature for Windows 11 as part of the June update KB5094126, available for all Windows 11 24H2 and 25H2 PCs. This feature enhances responsiveness during tasks like launching applications and accessing the Start menu by temporarily increasing CPU clock speed to its maximum for 1 to 3 seconds during actions that cause lag. Users must install update KB5094126 and check for a build number of 26200.8655 for 25H2 or 26100.8655 for 24H2 to access the feature. The activation of the Low Latency Profile may not be immediately visible, and the HWiNFO app can be used to monitor CPU activity for confirmation of its activation.

Windows 11’s CPU performance boost released today, enable it using these steps

Microsoft's June 2026 Patch Tuesday update, KB5094126, introduced the Low Latency Profile feature in Windows 11, aimed at improving responsiveness of core shell experiences like the Start menu and Action Center. This feature optimizes CPU performance by allowing it to quickly reach maximum frequency for one to three seconds during user interactions, enhancing the speed of actions such as opening the Start menu. Users must install the update and may need to enable the feature manually using ViVeTool if it is not activated automatically. The Low Latency Profile is designed to work without significantly impacting battery life or thermal performance. Other enhancements in the update include Shared Audio for Bluetooth headphones, Multi-App Camera functionality, and improved Task Manager capabilities.

Original Task Manager creator explains why it lies to you about CPU usage — former Microsoft engineer shows unique solution to a seemingly simple, but actually complicated, task

Dave Plummer, a former Microsoft engineer and architect of the original Task Manager, explained the complexities of measuring CPU usage. He noted that the process is not as simple as it seems, as CPU activity can vary across different cores and the timing of measurements can influence results. The Task Manager accounts for various states of CPU activity, including user mode, kernel mode, interrupt time, deferred procedure calls, and idle loops, making the measurement of CPU utilization a complex task rather than a straightforward one.

Microsoft now runs resource-hogging AppX Deployment Service at Windows 11 startup

Microsoft released a cumulative update for Windows 11, designated as KB5072033, which included a change to the AppX Deployment Service (Appxsvc), setting it to automatic startup to improve reliability. This change was not initially mentioned in the release notes but was later added, noting that it aims to enhance reliability in isolated scenarios. Users have expressed concerns about high resource consumption linked to this service, particularly on lower-spec machines. The update also introduced a standardized format for Windows Update titles to improve readability, announced that there will be no non-security preview update in the latter half of December 2025, and noted that Secure Boot certificates for most Windows devices will expire starting in June 2026. Additionally, Windows Updates will not include updates for Microsoft Store applications, with enterprise users advised to consult Configuration Manager for updates.
