What the Windows Low Latency Profile Does
The Windows low latency profile is a new performance setting that briefly pushes your CPU to higher speeds when you open key system features, reducing the time it takes for the Start menu, search, and Action Center to appear and respond. Instead of running the processor at a constant high speed, Windows uses this profile to spike the CPU to its maximum boost frequency for one to three seconds during these actions, then drop back down to normal levels. This gives you a Windows performance boost where it matters most: quick access to frequently used tools, smoother Windows Start menu speed, and snappier Windows search optimization. The feature currently targets native Windows components, with support for third‑party apps planned in a future update, so you’ll feel the improvement mainly in the core interface.
Check If the Optional Update Is Available
Microsoft has released the low latency profile as part of an optional Windows update, so you need to install that update before you can benefit from the new profile. This update brings Windows to builds 26200.8524 and 26100.8524 and includes other improvements like better Windows search recognition and USB stability. To see if it is available, open Settings, go to Windows Update, and look for an optional update that mentions performance or new features. Because Microsoft is rolling this out gradually, you might not see the option immediately in your region. According to Windows Latest, Microsoft has not officially enabled the feature everywhere yet, which is why some users may need to use a tool like ViVeTool to turn it on ahead of schedule.
Enable the Low Latency Profile Through Windows Update
Once you see the optional update that includes the low latency profile, enabling it is straightforward. In Settings, open Windows Update and click Check for updates to refresh the list. Under Optional updates or Preview updates, select the entry that aligns with the new build number, then start the download and installation. When prompted, restart your PC to apply the changes. After the restart, Windows automatically uses the new low latency profile for the Start menu, search, and Action Center, so you do not need to toggle a separate switch. You should notice improved Windows Start menu speed and slightly faster response when you tap the search box or open the notification panel. Remember that, for now, the Windows performance boost focuses on these built-in features rather than third‑party desktop apps.
Advanced Option: Turn It On Early with ViVeTool
If the low latency profile is not yet enabled for your device but you want the Windows performance boost right away, you can use the third‑party ViVeTool utility to activate hidden features. Download the latest ViVeTool release, extract it, then open Command Prompt as an administrator and navigate to the ViVeTool folder. From there, you run specific commands documented by Windows performance enthusiasts to toggle the low latency feature flag. According to Windows Latest, this method lets you “activate the new feature early using ViVeTool, though you'll have to jump through a few hoops and run a few commands in a Command Prompt window.” Treat this as an advanced option: it involves command-line work and may introduce minor bugs, so create a restore point and proceed only if you are comfortable reversing changes.
Other Improvements in the Same Optional Update
The optional update that delivers the Windows low latency profile also bundles several quality‑of‑life improvements that make upgrading more appealing. Windows search has been tuned to better recognize files and folders from as few as two characters, which helps the overall Windows search optimization story. There is new Shared Audio support so two pairs of Bluetooth headphones can play the same audio from one PC, ideal for couch co‑op gaming or watching a movie together. Task Manager now gives clearer insight into NPU performance and related processes, while Windows Camera can stream its feed to multiple apps at once to help with troubleshooting. You can also customize your user folder name during setup, plus enjoy more stable USB4 and USB3 connections that handle unexpected hardware faults with fewer errors.
