Microsoft is working on a Windows 11 update that aims to reduce startup times for some tasks, Windows Central reported.
The update includes a new high-performance mode that Windows Central’s sources call Low Latency Profile. The report said the mode has delivered up to 40% faster app load times and up to 70% faster interface launch times.
The feature improves performance by briefly pushing the computer’s CPU to its maximum frequency. This allows the processor to handle more operations per second while the task is starting.
Windows Insider Program testers using the Low Latency Profile report that each processor boost lasts one to three seconds. The boost starts when a user opens an app or loads an interface.
The performance boost reportedly works with Microsoft apps such as Edge and Outlook. It also applies to flyout interfaces such as the Start menu and some third-party apps.
However, it remains unclear which third-party apps qualify as “high priority tasks” that can trigger the Low Latency Profile CPU boost.
Windows Insider Program testers report that the Low Latency Profile works automatically and cannot be switched on or off manually. The feature activates when a high-priority task starts and remains invisible to users.
Windows Central’s sources said the impact on battery life and thermals is minimal because the CPU boost lasts only a few seconds at a time.
A Microsoft representative did not immediately respond to a request for comment.
The Low Latency Profile update is reportedly part of Microsoft’s Windows K2 project, which focuses on improving Windows 11 performance and making the operating system feel more responsive.
The report comes as Microsoft continues trying to increase Windows 11 adoption after a slower shift from Windows 10.
Support for Windows 10 ended in October 2025, but about 1 billion computers were still running the older operating system at the end of the year.
That figure represented nearly 43% of all Windows machines. As of April 2026, only 70% of machines in Microsoft’s ecosystem were running Windows 11.
The low adoption rate creates a security concern because Windows 10 vulnerabilities will no longer receive patches after the Extended Security Updates program ends. Upgrading to Windows 11 or another operating system remains the best way to protect a machine.
