Microsoft is expanding access to the Low Latency Profile (LLP) in Windows 11, bringing a noticeable performance boost to system interfaces for more users. The feature is included in the June 2026 optional update, identified as KB5095093. While this marks a wider release, Microsoft is still deploying it gradually throughout 2026, meaning not every PC will receive the change immediately upon installing the update.
How Low Latency Profile works
The Low Latency Profile is a hardware-level CPU scheduling technique designed to reduce input lag and improve responsiveness in the Windows shell. It operates by briefly increasing CPU utilization—typically for less than three seconds—when you interact with key system elements. This burst of processing power helps ensure that components like the Start menu, Notification Center, and Quick Settings open instantly without stutter.
This technology is not unique to Windows; similar features exist in macOS and Linux. However, for Windows users, particularly those on lower-end hardware, the impact can be significant. The profile is most beneficial for PCs with modest specifications, such as an Intel Core i3 processor or 8GB of RAM. On high-end machines with powerful CPUs and ample memory, the difference may be barely perceptible because those systems already handle these tasks efficiently.
What this means for you
If you use an older or budget-friendly PC, enabling Low Latency Profile can make your system feel noticeably faster and more responsive. In testing on a decade-old machine with 8GB of RAM, the feature made the interface feel almost as snappy as a fresh installation of Windows 11. The brief CPU spikes required to activate the profile are transient enough that they do not negatively impact overall system stability or battery life in any meaningful way.
It is important to note that the current rollout focuses on operating system elements. While Microsoft’s release notes mention improvements for apps, the feature is not yet active for third-party application launches. That functionality is expected to arrive in a future update, likely within the next month or two.
How to verify and enable Low Latency Profile
If you have installed KB5095093 but do not see immediate improvements, the feature may not be enabled on your device yet. You can verify if LLP is working by monitoring CPU usage with a tool like HWiNFO. Task Manager often lacks the high-frequency polling needed to catch these brief spikes, but HWiNFO can track rapid, transient per-core utilization changes.
To check for the effect, open HWiNFO and watch the CPU utilization graph. Then, open the Start menu or Notification Center. If you see a sharp, short-lived spike in CPU usage lasting less than three seconds, Low Latency Profile is active and working as intended.
If you prefer to force-enable the feature before it rolls out to your device, you can use ViVeTool, a third-party utility for managing Windows features. Download the latest version of ViVeTool and run the following command in an elevated Command Prompt or PowerShell window:
vivetool /enable /id:58989092
After executing the command, restart your computer. Once rebooted, you should notice reduced latency when opening system flyouts and menus. This manual enablement provides immediate access to the performance boost, allowing you to test its impact on your specific hardware configuration.
