▼ Summary
– Windows 11 optional update KB5089573 is the first release from Microsoft’s secret Project K2, which aims to improve performance through 2027.
– The update introduces a Low Latency Profile that briefly boosts CPU speed for important tasks, reducing lag and stutters.
– According to tests, this feature can deliver up to 70% faster flyouts and 40% quicker app launches.
– Users can manually install the preview update via Windows Update or the Microsoft Update Catalog, though the performance boost may take weeks to activate.

Microsoft is delivering on a prior promise with a new optional patch for Windows 11 that noticeably speeds up the system, particularly during specific tasks. Designated as update KB5089573, it introduces a Low Latency Profile designed to reduce lag and improve responsiveness.
This update is the first output from Microsoft’s internal Project K2, a long-term initiative aimed at steadily enhancing Windows 11 performance through 2027. The goal is to win back users by making the operating system feel snappier and more efficient.
The core of this improvement is a clever performance trick. When Windows 11 detects a critical action,like launching an app, opening the Start menu, or using the Search and Action Center,the Low Latency Profile briefly boosts the CPU clock speed to its maximum for up to three seconds. This short burst of power eliminates stutters and delays, making everyday interactions feel fluid.
While this technique has been standard in macOS and Linux for years, its arrival on Windows is a significant upgrade. Early testing by Microsoft Insiders confirms the gains, and independent tests from Windows Latest report dramatic improvements: up to 70 percent faster flyouts (those temporary floating menus) and up to 40 percent faster app launches. The overall effect is a noticeably more responsive desktop experience.
Currently, KB5089573 is an optional preview update, meaning it won’t install automatically. To get it ahead of the broader rollout, navigate to Settings → Windows Update → Advanced options → Optional updates and install it manually. Alternatively, you can download it directly from the Microsoft Update Catalog.
One important caveat: Microsoft is rolling out the Low Latency Profile feature gradually. Even after installing the update, it may take a few weeks before the performance boost activates on your system. The update also includes improvements to audio, the Task Manager, and the Camera app. The final, mandatory rollout for all Windows 11 users is scheduled for June 2026, as part of Patch Tuesday.
