Windows 11 gains a Low Latency Profile CPU boost via May 2026 update, unlockable now
Microsoft’s optional Windows 11 May 2026 update KB5089573 includes a CPU-boosting feature called Low Latency Profile that speeds up core UI flyouts (Start menu, Search, Action Center). Activation can be delayed by Microsoft’s CFR rollout, but you can force it now by installing the May optional update and using ViveTool with vivetool /enable /id:58989092, then reboot. Currently it improves UI fluidity but not app launches; a future update will expand the speed boost to apps. No special hardware required, and you can verify via faster UI loads or brief CPU spikes, or revert with /disable if needed.
