Windows 11 Low-Latency Profile Boosts App Startup by Up to 70%

Microsoft is testing a new feature in Windows 11 called Low-Latency Profile that temporarily boosts the CPU clock to accelerate app startup. The feature is hidden and not yet active in the Insider Program, but users can enable it via ViVeTool.

Microsoft tests CPU boost for faster app launch

Internal measurements from Microsoft show that apps like Outlook and Edge start up to 40% faster with the CPU boost. Windows elements such as the Start Menu can see improvements of up to 70%.

Microsoft developer Scott Hanselman defended the approach, stating that all modern operating systems, including macOS and Linux, use similar techniques. The feature is designed to reduce launch times by briefly running the CPU at a higher clock speed during the first few seconds of app opening.

The Low-Latency Profile is part of ongoing efforts to improve Windows 11 responsiveness. Microsoft has not confirmed when the feature will roll out to all users.
