Microsoft has rolled out a new low latency profile for Windows 11, aiming to make the Start menu, File Explorer and app launches feel snappier. The feature taps an extra burst of CPU power whenever users open menus or launch apps, according to test builds that Microsoft has shared with reviewers in early beta versions now.

Performance tests by Windows Central show the new profile noticeably speeds up interactions on the same hardware compared to the current public 25H2 build. Critics on social media worry that the CPU burst could drain batteries, but Microsoft’s VP Scott Hanselman defended the approach, noting that OSes—including macOS and Linux—use tricks to keep apps responsive.

Microsoft argues the short‑burst strategy saves energy overall, citing the “race to sleep” model where processors finish tasks quickly and return to low‑power states. By prioritizing interactive workloads, the OS can deliver snappier UI without a sustained increase in power draw, a technique already common in other big‑name operating systems today for users everywhere.

The low‑latency tweak arrives as Windows 11 continues to face scrutiny over performance and battery life. By blending hardware bursts with software tuning, Microsoft positions the update as a balanced solution. Users running recent builds should notice a tighter, more fluid interface, confirming the company’s claim that the tweak improves everyday workflow without extra cost.
