Microsoft says recent Windows 11 updates have improved system responsiveness and multitasking performance on computers equipped with 8GB of RAM. The company reports that everyday responsiveness has increased by around 20%, while multitasking performance has improved by as much as 40% in selected laboratory tests.
The improvements are attributed to a series of memory-management and software optimisation changes across Windows 11, Microsoft Edge and Microsoft 365 applications. These include more efficient memory compression, reduced background activity, faster suspension of inactive browser tabs and lower memory consumption by productivity software.
The changes could be particularly relevant for users who rely on entry-level laptops and budget desktop computers, especially as rising memory prices put pressure on the cost of new hardware.
Microsoft Reports 20% Improvement in Everyday Responsiveness
Microsoft's reported 20% improvement is based on telemetry measuring how quickly common Windows features respond to user actions.
The company says the measurements covered everyday activities involving Windows Search, the Start menu, right-click menus, Settings, Snipping Tool and File Explorer.
According to the supplied report, the improvements are included in Windows 11 version 26H2, build 6300.9550, released on September 29, 2026.
Microsoft has also reported gains in multitasking performance. In one laboratory test, an HP OmniBook 3 equipped with a Snapdragon X Plus processor and 8GB of RAM recorded improvements of up to 40%.
The test involved keeping multiple applications open, including 20 Microsoft Edge tabs, a 4K video, large Word, PowerPoint and Excel files, Outlook and File Explorer. Microsoft compared the time required to complete the workload across different Windows 11 builds.
These figures represent results from specific testing conditions and should not be treated as guaranteed improvements on every computer.
Can an 8GB PC Perform Like an Older 16GB System?
Microsoft also says that an 8GB Windows PC can match the performance of a 16GB computer from 2021 in certain everyday scenarios.
The company's comparison reportedly covered web browsing, AI-assisted browser features such as background blur and face detection, and 4K video export.
However, this does not mean that 8GB and 16GB computers offer identical performance across all workloads. Hardware specifications, processor capabilities, storage speed and application requirements continue to influence the overall experience.
Microsoft acknowledges that users working with demanding creative applications, large datasets and intensive multitasking can still benefit from additional RAM.
Memory Compression Helps Keep More Data Available
One of the major improvements involves Windows memory compression.
Memory compression allows the operating system to store more data within available RAM by compressing information rather than immediately transferring it to slower storage. This can reduce the need to reload applications and browser tabs when users switch between tasks.
Microsoft says its latest optimisations allow Windows to keep up to 2GB more active data in memory instead of moving it to storage.
These changes are particularly relevant to computers with limited RAM, where frequent movement of data between memory and storage can affect responsiveness.
Background Processes Receive Lower Priority
Microsoft has also adjusted how Windows manages background processes.
Activities such as Search indexing can be reduced or throttled when the system detects that someone is actively using the computer. This is intended to prevent less important background operations from competing with tasks that require immediate system resources.
The changes may be especially noticeable after restarting a computer following an update, when Windows can continue performing background setup and maintenance activities.
Microsoft Edge Puts Inactive Tabs to Sleep Faster
Browser tabs can consume considerable memory, particularly when users keep multiple websites open throughout the day.
Microsoft has introduced changes to Edge that reportedly place inactive tabs into sleep mode after 15 minutes, compared with the earlier waiting period of up to two hours.
Sleeping tabs release memory while retaining their page state, allowing users to return to them later. Microsoft also says that changes to background browser processes have improved launch speed by approximately 33%.
Microsoft 365 Applications Use Less RAM
Memory optimisation has also been extended to Microsoft's productivity applications.
According to the company, Word, PowerPoint, Excel and Outlook together now consume approximately 360MB less RAM than before.
Other reported improvements include:
Widgets: Loading the feature only when users open it can save around 200MB of memory.
Microsoft Teams: Efficiency Mode can reduce the application's impact on system resources on supported configurations.
Combined optimisations: Microsoft reports that committed-memory growth has been reduced by as much as 900MB.
These changes are intended to leave more system resources available for applications that users actively operate.
More Windows Optimisations Are Planned
Microsoft says additional memory-saving improvements are under development.
One planned approach involves allowing different Windows features to share common software components rather than loading separate copies. Search and Widgets, for example, are expected to share a web engine.
The company is also planning to optimise applications built using its WinUI 3 framework. These improvements could affect File Explorer, Notepad, Paint and the newer Windows search experience.
If implemented successfully, the changes could reduce memory consumption and improve application launch times without requiring users to upgrade their computer hardware.
8GB RAM Still Has Practical Limitations
Despite the reported improvements, 8GB of RAM is not suitable for every computing requirement.
Gaming, professional video editing, software development, virtual machines and workloads involving large datasets can require substantially more memory.
Performance also depends on the processor, storage technology, graphics requirements and the number of applications running simultaneously.
Microsoft's optimisation work is primarily aimed at improving everyday productivity rather than making lower-memory computers equivalent to high-performance systems.
For users who mainly browse the internet, work with documents, attend online meetings and perform routine office tasks, the improvements could help extend the useful life of existing computers.
Rising Memory Prices Make Software Optimisation More Important
The timing of Microsoft's announcement is notable because higher memory prices have increased the cost pressure on computer manufacturers and consumers.
Growing demand from AI infrastructure and data centres has contributed to changes in the global memory market. More efficient operating systems could therefore help manufacturers maintain affordable computer configurations while improving the experience for everyday users.
Microsoft's latest approach focuses on making better use of available hardware rather than requiring every user to purchase a computer with more RAM.
Ultimately, the reported improvements suggest that software optimisation can make 8GB Windows 11 computers more practical for routine workloads. However, users with demanding applications should continue to consider higher-memory configurations when purchasing or upgrading a computer.
