The report highlights that it’s called patch KB5089573 and it includes the “Low Latency Profile” capability. Microsoft is following through on a previous disclosure with a fresh optional patch for Windows 11 that makes the operating system genuinely faster, especially in certain situations.
According to the latest update, in short, the aim of the Windows K2 project is to consistently improve Windows 11 performance all the way through 2027 in the hopes of winning back users. Windows Central reports that KB5089573 is the first patch to come out of the secret Windows K2 project.
As part of the ongoing story, tESTED: Windows 11's upcoming "Low Latency Profile" mode brings genuine performance improvements to the OS, speeding up flyout and app debuts significantly.We've benchmarked opening some apps on video with the Low Latency Profile enabled and disabled, and you can see… pic.twitter.com/BCNtsXmx31.
The report highlights that microsoft describes the key improvement in this patch: “[General Performance] This patch accelerates app arrival and core shell experiences such as Start menu, Search, and Action Center.”.
As part of the ongoing story, it refers to the fresh Low Latency Profile capability that causes Windows to briefly boost CPU clock speed to full power (for a maximum of three seconds) whenever the operating system initiates an important task, like launching an app or opening the Start menu. With it, lag and stutters should be a thing of the past. It’s a small note but an impactful one.
As part of the ongoing story, according to Microsoft, Insider testers who have been using Low Latency Profile with their beta versions of Windows have confirmed the performance gains. And according to Windows Current, who has also tested the Low Latency Profile, you may see performance gains of up to 70 percent when opening flyouts (temporary, floating control panels or menus in user interfaces) and up to 40 percent when launching apps. This should make Windows 11 feel faster overall. This technique isn’t novel, as both macOS and Linux have been doing this for years.
As part of the ongoing story, if you want to install it before it’s rolled out to everyone next month, look for it in Settings → Windows Revision → Advanced options → Optional updates, then install it manually. Or you can download the patch directly via the Microsoft Revision Catalog. The optional Windows 11 patch KB5089573 is currently optional and in preview stage, so it won’t be installed on your system by default yet.
Industry observers note that it may take up to a few weeks to get the improvement. Note that Microsoft is rolling out this capability gradually, so you may not actually get the performance boost immediately after installing the patch.
Industry observers note that the final rollout of KB5089573 to all Windows 11 users is expected to take place as scheduled on Patch Tuesday in June 2026. In addition to Low Latency Profile, KB5089573 brings improvements to audio, the Task Manager, and the Camera app.
