Microsoft has released a new Windows 11 update that introduces a major performance improvement designed to make PCs feel faster during everyday use. The optional preview update, identified as KB5089573, adds a new feature called Low Latency Profile that temporarily boosts CPU performance during important system tasks.
The release represents the first public result of Microsoft’s internal Windows K2 project. The initiative focuses on improving Windows 11 performance through 2027 as Microsoft attempts to enhance responsiveness and improve user satisfaction across the operating system.
According to Microsoft, the Windows 11 update accelerates app launches and improves “core shell experiences such as Start menu, Search, and Action Center.” Early testing suggests the improvements may significantly reduce delays and stutters that users often experience while navigating the operating system.
Windows 11 update introduces Low Latency Profile
The Low Latency Profile feature works by temporarily increasing CPU clock speeds whenever Windows detects an important action. The operating system activates the boost when users launch apps, open the Start menu, or interact with critical interface elements.
Microsoft says the boost lasts for a maximum of three seconds. During that short period, Windows prioritizes responsiveness to deliver smoother interactions and quicker reactions. The approach aims to improve how fast Windows feels during daily tasks rather than focusing only on benchmark scores.
Industry analysts note that similar optimization methods have existed for years on macOS and Linux systems. However, Microsoft is now applying the technique directly within Windows 11 to improve overall responsiveness.

Reports from Insider testers indicate that the feature delivers noticeable improvements. Windows Latest reported performance gains of up to 70 percent when opening flyouts and temporary control panels. App launch speeds reportedly improved by as much as 40 percent in some testing environments.
Those improvements may vary depending on hardware and system configuration. However, even moderate gains could make Windows 11 feel smoother and more responsive for millions of users.
The Windows 11 update arrives as Microsoft continues to face criticism over operating system performance. Since Windows 11 launched, some users have reported slow animations, delayed menus, and background processes affecting responsiveness.
Microsoft focuses on faster Windows experiences
The Windows K2 project appears to represent a broader strategy inside Microsoft to modernize the Windows experience. Rather than introducing only visual changes or AI features, the company is increasingly focusing on improving speed and reliability.
Faster app launches and smoother menus can significantly improve daily user experience. Even small delays in opening system panels or launching applications often create frustration for users over time.
Microsoft hopes the Windows 11 update will help address those concerns. By improving responsiveness at the system level, the company aims to make Windows 11 feel more polished and competitive against rival operating systems.

In addition to the Low Latency Profile feature, KB5089573 also includes several smaller improvements. Microsoft says the update enhances audio performance, improves Task Manager stability, and adds refinements to the Camera app.
These changes may not receive as much attention as the performance enhancements. However, they contribute to Microsoft’s larger effort to refine the Windows 11 experience ahead of future releases.
Because the release remains in preview stage, Microsoft is rolling out the feature gradually. Users who install the update may not immediately receive the performance improvements linked to Low Latency Profile.
The company says the rollout may take several weeks before all eligible systems gain access to the feature. Microsoft often uses phased rollouts to monitor stability and identify potential issues before wider deployment.
How to install the Windows 11 update
Users who want early access to the update can install it manually through the Windows Update section in Settings. The release appears under Advanced Options and Optional Updates.
Users can also download KB5089573 directly through the Microsoft Update Catalog. Since the release remains optional, systems will not automatically install it during standard update cycles.
Microsoft expects the broader rollout to begin during Patch Tuesday in June 2026. Once that rollout starts, the Windows 11 update should reach a much larger number of devices worldwide.

The introduction of Low Latency Profile suggests Microsoft is placing greater emphasis on responsiveness and everyday usability. Many users judge performance based on how quickly menus open or how fast apps launch rather than raw benchmark numbers.
If the reported performance gains continue during wider deployment, KB5089573 could become one of Microsoft’s most important performance-focused Windows releases in recent years. The update may also signal a broader shift toward making Windows 11 faster, smoother, and more efficient over the next several years.
