Microsoft is improving memory management, although the benefits are far from universal.

Windows 11 26H2 is beginning to show measurable reductions in memory consumption on some computers, with early user reports indicating that the operating system can use up to 2 gigabytes less RAM immediately after startup compared with Windows 11 25H2. The improvement could make the system more efficient, but current results vary considerably depending on hardware and background software.
One reported case involving a computer with 48 GB of RAM showed startup memory use falling from approximately 6.9 GB to between 4.8 and 5 GB after the update. Another system with 32 GB dropped from 9.1 GB to around 7.5 GB, freeing roughly 1.6 GB. Some users have reported reductions approaching 3 GB, while others have seen almost no change.
Those differences highlight an important reality of Windows memory management. Identical RAM capacity does not necessarily produce identical consumption. Startup applications, manufacturer software, background services and hardware configuration can all significantly influence how much memory the operating system appears to use while idle.
The most concerning results involve computers equipped with only 8 GB of RAM. In one documented case, Windows 11 26H2 consumed around 7.4 GB of the 7.7 GB available, equivalent to approximately 96 percent of usable memory. Only about 333 megabytes remained free.
That level of saturation can force Windows to rely more heavily on the SSD paging file, moving data between RAM and storage when physical memory becomes insufficient. Modern solid state drives make that process faster than older hard drives, but it still introduces more latency than accessing data directly from RAM. The result can be noticeable pauses or reduced responsiveness when several applications are open simultaneously.
The situation is particularly relevant because lower cost laptops continue to ship with 8 GB or 16 GB of memory. Rising memory prices could reinforce that trend, making software optimization increasingly important for users who cannot simply compensate by installing more RAM.
Microsoft is expected to continue refining memory management as Windows 11 26H2 evolves. The early data suggest that progress is possible, but they also show that reducing baseline consumption does not automatically solve the limitations of entry level hardware.
The update may make Windows lighter. For many 8 GB machines, however, there is still very little room left to breathe.
