Windows 11 26H2 update brings speed boost and lower RAM use for some PCs

The Windows 11 26H2 update quietly turns on a Low Latency Profile and can cut memory use on certain PCs. Users are seeing snappier performance without a big system overhaul.

Some Windows 11 users are noticing a real difference after installing the 26H2 update. Their PCs feel quicker. For a few, memory use drops right after a reboot. The change is subtle, but it matters.

Microsoft calls Windows 11 version 26H2 the next annual feature update. It arrives as a servicing package, so installation is fast on supported devices. The company says this is a "predictable and low-disruption update." The code base matches versions 25H2 and 24H2. That means a short install and few compatibility headaches, according to official documentation for IT professionals.

Microsoft's release-health page confirms that 26H2 contains the recently announced features from Windows 11 versions 25H2 and 24H2, and uses the same servicing path as those releases.

Performance gains and memory savings

The 26H2 update is an enablement package. Most features have been rolling out in monthly patches, but now more users get the optimizations. Windows Latest reports that apps like WhatsApp, Calculator, and Weather open faster. The Low Latency Profile is the reason. Not every PC gets these changes at once. Microsoft staggers the rollout.

Some users are seeing less RAM used after the update. On a three-year-old laptop with 16GB of memory, Windows Latest saw RAM drop from over 10GB to about 7GB after a restart. Reddit users shared similar stories. One saw a 2GB drop on a 48GB system. Another watched usage fall from 9.1GB to 7.5GB on a 32GB machine. Not all PCs benefit. An 8GB system showed no change. Hardware and usage matter. TechRadar and HardwareCooking both cite user reports of RAM dropping by 1.6-2.0 GB after upgrading to 26H2 on systems with 16GB to 48GB of RAM. The effect is not universal.

What is actually changing under the hood?

Microsoft does not officially claim that 26H2 cuts RAM use. The company says startup apps, cached data, and browser tabs all affect memory numbers. Still, Microsoft has said it wants Windows 11 to feel faster under heavy load and use less memory, especially on 8GB systems. Teams are working on memory management, memory compression, WinUI, and WebView2.

Independent reports show Microsoft has been trying to shrink Windows 11's memory footprint since at least August 2026. The lower RAM use some users see fits this bigger effort. It is not a headline feature of 26H2. A TechRadar analysis says these changes are part of a long-term push, not just one update.

A preview-focused benchmark from WindowsForum.com found that memory footprint changes were small in controlled workloads, suggesting that the larger RAM savings are not universal and may depend on hardware, software load, and background services.

Other small tweaks are rolling out too. File Explorer and Search now preload less and respond faster. WinUI changes keep refining the interface. These small steps, plus the Low Latency Profile, make Windows 11 feel quicker. No big new feature needed.

For those watching desktop environments, this is similar to what KDE Plasma did by focusing on speed and stability instead of looks.

Microsoft's plan with 26H2 is simple. Make Windows 11 faster and more efficient without forcing users to relearn the system. Quietly turn on features that speed up daily tasks and sometimes lower memory use. The company is tackling old complaints about Windows bloat. The result? A system that feels lighter, even if most changes are invisible. For users who care about speed, that's a win.
