Many computers still leave the factory with 8 GB of memory, even as the price of additional RAM has climbed sharply in response to demand from large-scale AI infrastructure.
On those machines the operating system and a handful of open applications can quickly exhaust the available capacity, forcing data onto slower storage and producing the familiar pauses when switching back to an earlier window or tab.
Microsoft has spent much of 2026 adjusting how Windows 11 manages that constraint.
The changes ship with Windows 11 version 26H2, beginning with build 26300.9818.
In laboratory measurements, the company reports that everyday interactions such as opening the Start menu, searching, launching File Explorer, or opening Settings are up to 20% faster than on the builds available at the start of the year.
A scripted multitasking sequence that opened 20 browser tabs, a 4K video, large Office documents, Outlook, and File Explorer completed up to 40% more quickly on the same 8 GB hardware.
The figures come from controlled lab tests; real-world results vary with the specific combination of applications and background processes.
But still, it's a gain.
Contributing to this, include memory compression that has been tweaked so that Windows can retain up to 2 GB more of actively used data in RAM rather than writing it to the page file.
Foreground tasks receive brief priority while background work such as indexing is deferred.
On systems with 8 GB or less, the Widgets board no longer stays resident when closed, freeing roughly 200 MB. Microsoft Edge now suspends inactive tabs after fifteen minutes instead of two hours. Teams can enable Efficiency Mode by default, and the combined footprint of Windows, Edge, and the Microsoft 365 applications grew by as much as 900 MB less in the multitasking trials. Microsoft 365 apps themselves account for about 360 MB of that reduction.
Independent measurements published by Windows Central on an Acer laptop with 8 GB of LPDDR5x memory showed a similar direction of change.
After a clean boot, total RAM use fell from 5.3 GB on a year-old 25H2 build to 4.1 GB on 26H2.
Under a moderate workload the available free memory roughly doubled, and under a heavier combination of browser tabs, Office files, and other applications the committed memory figure dropped by several gigabytes.
Disk activity spikes still occurred when the system was under pressure, but they were less severe.
Microsoft notes that the improvements do not turn an 8 GB machine into the equivalent of a system with twice the memory for sustained heavy work such as large-scale video editing or 3D modeling.
A commissioned comparison of a 2026 8 GB laptop against a 2021 16 GB model found the newer machine competitive on several CPU-bound and browser tasks, yet the company continues to recommend 16 GB or more for demanding concurrent workloads.
The updates themselves arrive through the normal Windows Update channel once the device is on 26H2 build 26300.9818 or later; some of the application-level savings also require current versions of Edge, Teams, and the Microsoft 365 suite.
The net effect is a set of incremental reductions in how quickly an 8 GB system reaches the point where it must page to disk, together with modest gains in the speed of common interface actions.
