Microsoft has started rolling out a Windows 11 update that goes after one of the most common complaints about the operating system: it can feel sluggish in daily use. The optional KB5089573 update is aimed at making the system faster, more responsive, and more reliable, with performance improvements taking priority over cosmetic changes.
The update is also notable because it is the first Windows OS release prepared specifically to speed up Windows 11 through Microsoft’s Windows K2 initiative. That means the focus is on core behavior, including how quickly the system reacts when users open apps, access the Start menu, or move through other everyday shell experiences.
Performance is the main target
Microsoft says the update brings general performance improvements across the system. App launch speed is part of that work, along with core shell experiences such as Start menu, Search, and Action Center.
The company also points to better reliability on the sign-in screen and lock screen. Other areas included in the update are File Explorer, touch gestures on touchscreen devices, and the process of changing themes in Settings.
Low Latency Profile is the key change
The most noticeable gains are tied to the Low Latency Profile. This mechanism works by pushing CPU frequency higher in short bursts so specific actions can complete more quickly.
Microsoft tested the changes with Insiders for several weeks, and internal testing discussed by Windows Central reported visible results when the feature was active. In those tests, system flyouts appeared up to 70% faster, while app launches improved by up to 40%.
Those gains are meant to show up in normal use as well. When the improvement is active, Windows 11 should feel more responsive and react more quickly to user input.
Rollout will not reach everyone at once
Even though KB5089573 is already available, the performance changes will not be enabled immediately for every device. Microsoft says the rollout is gradual, so some users may not see the new behavior right after installing the update.
That staged approach gives Microsoft time to keep the release stable before expanding it to more devices. In practice, the performance boost should appear over the coming weeks as the company opens the rollout more broadly.
More than a speed update
The package is not limited to performance tuning. Microsoft also added support for Bluetooth sharing to two devices at the same time, plus an option to name a device during setup.
Task Manager also gets updates as part of the package. That makes KB5089573 a broader quality update, even though the main headline is the push to make Windows 11 feel faster in everyday use.
How to install it
Because KB5089573 is optional, users need to install it manually. The path is Windows Settings > Windows Update > Advanced options > Optional updates, then select the update available for installation.
Another option is to turn on “Get the latest updates as soon as they’re available” on the main Windows Update page. After that, checking for updates again can help the optional OS update arrive sooner once it is available for the device.
Microsoft has been putting more attention on Windows quality in recent months, and KB5089573 shows that effort in a more practical form. Rather than adding visible extras first, this release is meant to reduce the sense that Windows 11 is slow when users need it to move quickly.
