low latency profile

The low latency profile is a Windows 11 performance feature introduced in the June 2026 cumulative update KB5094126 for versions 24H2 and 25H2, and later expanded via KB5095093. It briefly raises CPU frequency during interactive tasks such as launching apps, opening Start, using Search, and navigating File Explorer or context menus. The goal is to make common desktop actions feel faster without requiring new hardware. This feature represents a shift in Microsoft's approach to responsiveness, focusing on perceived speed during user interactions rather than raw benchmark performance. It is particularly beneficial for older PCs, helping them feel less sluggish. The low latency profile is not a visible app or setting but works at the scheduler and power behavior layer.
