Has Anyone Tried KB5089573?

Just came across news about Windows 11’s optional update KB5089573. Apparently it includes a new “Low Latency Profile” feature that speeds up app launches, the Start menu, Search, and other parts of the UI by briefly boosting CPU performance. Has anyone installed it yet?

I’ve been following the Windows K2 project rumors for a while, and this seems like the first visible result. If Microsoft continues improving performance through 2027 like they’re planning, Windows 11 could finally shed its reputation for feeling sluggish. For once, this looks like an update that’s actually focused on making PCs faster instead of just adding new features.

I’m cautiously optimistic. Microsoft has talked about performance improvements before, but Windows 11 still feels heavier than Windows 10 on some systems. I’ll wait until the June rollout and see what real users are saying.

If this works as advertised, it could be great for older hardware. My budget laptop runs Windows 11 fine, but opening File Explorer or Search always has a slight delay. Reports claiming up to 40% faster app launches sound promising.

What’s interesting is that Microsoft isn’t really inventing something new here. macOS and Linux have used similar “race-to-sleep” techniques for years. The CPU ramps up briefly, completes the task faster, then returns to a low-power state. It’s a smart way to improve responsiveness without constantly increasing power consumption.

I installed it on my test machine yesterday. The difference isn’t massive, but Windows definitely feels snappier. The Start menu opens instantly, and apps like Edge and Outlook seem to launch faster than before.
