What makes KB5089573 different from other updates?
According to Microsoft's changelog, KB5089573 introduces "Low Latency Profile" improvements that maximise CPU frequency in very short bursts. This results in system flyouts appearing up to 70% faster and app launches speeding up by 40%.
The update accelerates core Windows experiences including the Start menu, Search, and Action Centre. Unlike typical maintenance updates, this one targets fundamental performance bottlenecks rather than just fixing bugs.
Microsoft has been testing these changes with Windows Insiders for weeks, with testers reporting noticeably snappier system responses. The improvements focus on reducing app overhead and making Windows 11 feel more responsive to user input.
What is the Windows K2 effort?
The Windows K2 effort represents Microsoft's commitment to addressing the most common criticisms of Windows 11. KB5089573 is the first major update designed specifically under this initiative.
Microsoft launched K2 after acknowledging user frustrations with Windows 11's performance and reliability. The effort focuses on foundational OS improvements rather than adding new features that might complicate the system further.
This approach differs from Microsoft's previous update strategy, which often prioritised new functionality over core system stability. The K2 effort signals a return to focusing on what users actually need: a faster, more reliable operating system.
Additional improvements in KB5089573
Beyond performance gains, KB5089573 improves Windows reliability across multiple areas. The update enhances stability on sign-in and lock screens, fixes File Explorer issues, and resolves problems with touch gestures on touchscreen devices.
New features include:
- Bluetooth sharing with two devices simultaneously
- Device naming during initial setup
- Task Manager updates for better system monitoring
- Theme changing improvements in Settings
These additions complement the core performance improvements, creating a more polished overall experience. The reliability fixes address common pain points that have frustrated Windows 11 users since launch.
How to install Windows 11 KB5089573 update
You'll need to manually install KB5089573 as it's classified as an optional update. Go to Windows Settings > Windows Update > Advanced options > Optional updates and select KB5089573 to install.
Alternatively, enable "Get the latest updates as soon as they're available" on the main Windows Update page, then click "Check for updates." This setting ensures you receive optional updates automatically when available for your device.
Microsoft warns that performance improvements roll out gradually over several weeks after installation. You might not notice the speed gains immediately, as the company enables the Low Latency Profile features in waves rather than all at once.
Availability and compatibility
KB5089573 is free for all Windows 11 users globally, including those in the UAE. The update works on all Windows 11 versions and doesn't require specific hardware beyond standard Windows 11 requirements.
Microsoft is rolling out the performance improvements gradually, meaning the speed gains may take several weeks to fully activate on your system. This staged approach helps the company monitor the update's impact and ensure stability across different hardware configurations.
