Microsoft Rolls Out Windows 11 26H2, Cutting RAM Use by Up to 2GB

Q: Why does Microsoft's massive Windows 11 memory upgrade leave 8GB PC owners completely in the dark?

Because the early RAM savings in Windows 11 26H2 appear to come from trimming cached overhead and scaling back memory Windows only uses when plenty is available. On 32GB and 48GB PCs, that can show up as a visible 1.5GB to 2GB drop. On an 8GB machine already sitting near 96% usage, there is far less reclaimable headroom, so the same optimizations barely register. That fits how Windows memory management usually works. Systems with more RAM allow the OS to keep more data cached, preload more components, and tolerate heavier background frameworks such as WebView2 and Chromium-based elements. When Microsoft reduces that overhead, high-memory PCs show the biggest before-and-after difference. Low-memory PCs are already constrained and often paging to disk, so they do not get the same dramatic “freed RAM” result. It also matters that 26H2 is mostly an enablement package for code already delivered through 24H2 and 25H2 monthly updates. In other words, this is not a full redesign that suddenly makes 8GB systems light and fast. Microsoft has said memory optimization for “8GB and above” is an ongoing effort through the end of 2026, including a more efficient memory allocator, WinUI 3 tuning, and lower overhead in Chromium and WebView2 components. So 8GB owners are not being ignored; they are waiting for a longer optimization campaign whose earliest visible gains are landing on higher-end machines first.

Windows 11 26H2 is rolling out globally, with user reports showing memory use falling by as much as 2GB after installation.
Reddit and X posts cited in the report show the gains mainly on higher-memory PCs: one 48GB system dropped by 2GB, while a 32GB machine fell from 9.1GB to 7.5GB.
8GB systems appear to be missing out. One user reported no change after updating, with Windows 11 still consuming 7.4GB—about 96% of total memory.
The mixed results suggest Microsoft is improving memory management, but the update has yet to deliver meaningful relief for lower-spec PCs that most need it.
