Users testing the Windows 11 26H2 build have reported a noticeable drop in memory consumption when the system is idle. In a test on a 16GB RAM laptop, idle usage fell from 10GB to 7GB, leaving 8.8GB free alongside 4GB of cached memory. Community observations on Reddit and in reports from Windows Latest indicate reductions ranging from 2GB to 3GB during idle periods. The update also introduces a Low Latency Profile that temporarily raises CPU frequencies to maximum for one to three seconds after an application starts. This brief boost appears to accelerate launch times, particularly on lower-spec hardware. Testing by Windows Latest showed Microsoft Edge and Outlook opening about 40% faster, while elements such as the Start Menu responded up to 70% more quickly. These changes are not highlighted in official release notes but have been confirmed through user measurements and internal testing.
