Microsoft is working on a Windows 11 update designed to accelerate the start-up times for certain tasks, according to a report by Windows Central. The new high-performance mode — which Windows Central’s sources call Low Latency Profile — has reportedly resulted in up to 40% faster app load times and 70% faster interface launch times.
The performance boost is achieved by ramping up the computer’s CPU to max frequency in short bursts, allowing it to execute the highest number of operations each second it’s in use.
The Windows Insider Program testers who are currently using Low Latency Profile mode report that each processor boost lasts one to three seconds and begins when you start an app or load an interface.
The performance boost kicks in for Microsoft applications such as Edge and Outlook, flyout interfaces like the Start menu and a variety of third-party applications — though it’s unclear which third-party applications count as «high-priority tasks» that activate the Low Latency Profile CPU boost.
The Low Latency Profile update is reportedly part of Microsoft’s Windows K2 project, a concerted effort to increase Windows 11’s performance and make the operating system feel more responsive. Microsoft’s latest OS hasn’t exactly been embraced with open arms, so it makes sense that the company is trying to add new features that incentivize adoption.
Despite support ending for Windows 10 in October 2025, around 1 billion computers were still running on the outdated OS at the end of the year — a staggering figure representing nearly 43% of all Windows machines. And while more people are making the switch to Windows 11 now, only 70% of machines in Microsoft’s ecosystem are running the latest OS as of April 2026.
The low adoption numbers represent a serious security issue, since existing Windows 10 vulnerabilities won’t be patched after the Extended Security Updates program comes to an end. Upgrading to Windows 11 — or a competing OS — is the best way to protect your machine.
Windows Insider Program testers report that Low Latency Profile mode is an automatic, untoggleable feature that triggers upon the startup of a high-priority task, remaining invisible to the user. Windows Central’s sources claim that the «impact on battery life and thermals [is] minimal,» since the CPU boost only happens for a couple of seconds at a time.
