Microsoft says “you can do more, even with 8 GB” of RAM as Windows 11 gets faster

• Windows 11 is up to 20 percent more responsive, and multitasking is up to 40 percent faster on 8GB PCs, according to Microsoft’s tests.
• Improved memory compression allows Windows 11 to keep up to 2GB more active data in memory instead of moving it to slower storage.
• Microsoft reduced committed-memory growth by up to 900MB across Windows 11, Edge, and Microsoft 365 apps.
• Upcoming improvements include smarter memory compression, shared app components, and more efficient WinUI 3 applications.

Microsoft is providing an update on its ongoing efforts to make Windows 11 faster and more efficient on computers with 8GB of memory, highlighting improvements delivered throughout 2026 and outlining what’s coming next.

Although the company has been working on these optimizations throughout the year, the latest improvements are available on Windows 11 build 26300.9818 (KB5127936) or later.

The work is part of Microsoft’s broader Windows K2 initiative, which focuses on making the operating system more reliable and responsive without requiring users to upgrade their hardware.

In the latest announcement, Pavan Davuluri, Microsoft’s Executive Vice President of Windows + Devices, explained that the company has been improving the entire Windows stack, from the kernel to the shell and apps, to deliver a better experience for devices featuring 8GB of RAM.

The improvements build on the memory optimization efforts the company introduced earlier this year and focus on using available memory better, prioritizing important interactions, and reducing memory consumption across Windows and applications.

Windows 11 is up to 20 percent more responsive on 8GB PCs

One of the most noticeable improvements involves everyday interactions. Microsoft says Windows 11 can now respond up to 20 percent faster when opening Start, searching, right-clicking, opening Settings, launching Snipping Tool, and opening File Explorer.

The company compared telemetry measurements from Windows 11 builds 26300.9550 and 26200.7628, using January 2026 as the baseline.

Windows now prioritizes user actions instead of letting background activities compete unnecessarily for system resources. For example, the operating system can temporarily reduce background tasks, such as search indexing, while you’re actively using the computer.

Microsoft has also improved how Windows 11 launches Microsoft Edge. When you open a link or launch Edge from Start, the browser may already be running in the background. The operating system can connect to the existing process instead of searching for and starting it again, making the browser open up to 33 percent faster. This improvement requires Windows 11 build 26300.9818 or later and Edge 150 or later.

Microsoft Teams is also receiving improvements. On 8GB PCs, the app can enable Efficiency Mode by default, helping it launch up to 20 percent faster while reducing resource consumption.

Windows 11 can keep up to 2GB more data in memory

Another important improvement involves how Windows 11 manages available memory.

Opening Task Manager on an 8GB computer can sometimes show that most memory is already in use. However, high memory usage doesn’t necessarily indicate a problem. The system uses available memory to keep apps and frequently accessed data ready.

When the system needs more room, it can compress less-active data or move it to the storage drive. However, retrieving information from storage is slower than accessing it directly from memory. This is why switching back to an app or browser tab can sometimes take longer than expected.

Microsoft has refined memory compression and how the operating system decides when to keep data in memory, move it to storage, or retrieve it.

As a result, Windows 11 can now keep up to 2GB more active data in memory instead of moving it to slower storage. This should help applications and browser tabs remain ready when you return to them, reducing unnecessary reloads and delays.

Windows 11 multitasking is up to 40 percent faster

Microsoft is also reporting significant improvements when running multiple apps simultaneously.

According to the company, multitasking on 8GB computers is now up to 40 percent faster compared with January 2026 builds.

To measure the improvement, Microsoft tested a demanding workload on an HP OmniBook 3 with 8GB of memory and a Snapdragon X Plus 8-Core processor.

The test involved opening 20 Microsoft Edge tabs, playing a 4K video, opening large Word, PowerPoint, and Excel files, and launching Outlook and File Explorer while keeping everything running.

The company compared Windows 11 builds 26200.7623 and 26200.9445 on the same computer. The newer build completed the workflow up to 40 percent faster.

Microsoft is reducing memory usage across Windows and its apps

The improvements aren’t limited to Windows itself. The software giant has also been working to reduce memory consumption across the operating system, Microsoft Edge, and Microsoft 365.

In its multitasking tests, the company reports reducing committed-memory growth by up to 900MB on 8GB computers.

Improvements across Word, PowerPoint, Excel, and Outlook account for approximately 360MB in memory savings. Microsoft says these gains come partly from more efficient memory organization and allocation.

The company is also reducing memory consumption for features that aren’t actively being used.

For example, Widgets now loads only when opened on computers with 8GB of memory or less. This reduces memory commitment by approximately 200MB while the feature remains closed.

Microsoft Edge is also changing how it manages inactive tabs. Instead of putting tabs to sleep after two hours, the browser now uses a 15-minute default timeout, reducing memory consumption from tabs you’re not actively using.

Third-party apps can also benefit from these platform improvements. Microsoft specifically mentioned WhatsApp, which is already seeing double-digit memory improvements in its Windows application.

Microsoft plans more Windows 11 performance improvements

Microsoft says its work on Windows performance and memory optimization isn’t finished. The company outlined several improvements it’s developing for the coming months.

First, the company plans to make memory compression smarter and more efficient, helping Windows 11 keep more useful data in faster memory.

The software giant is also working to reduce duplicated components across Windows apps and features. Search and Widgets will eventually share one web engine, while OneDrive and Photos will share another, reducing the memory overhead associated with maintaining separate components.

Microsoft is also improving built-in applications with WinUI 3, including File Explorer, Notepad, Paint, and the new Windows Search experience. The goal is to make these apps launch faster and consume less memory.

Another focus is working with computer manufacturers and processor partners to reduce the memory reserved for hardware, leaving more available for Windows and apps.

Finally, the company says it will continue working with third-party developers to help their apps use memory more efficiently.

Does 8GB of memory still make sense for Windows 11?

Microsoft’s announcement acknowledges that Windows 11 needs to work better on computers with limited hardware resources.

For everyday activities, including browsing, writing documents, attending video meetings, and managing files, 8GB of memory can still be sufficient. However, Microsoft recommends 16GB or more for demanding workloads such as 3D modeling, advanced video editing, and large-scale data processing.

The company also highlighted improvements in processor technology. In third-party testing commissioned by Microsoft, a 2026 Dell XPS 13 with 8GB of memory delivered up to 94 percent faster multi-core processor performance than a 2021 model with the same memory capacity.

The newer computer also performed approximately as well as a 2021 configuration with 16GB of memory across several tested workloads, including processor performance, web browsing, AI-powered web tasks, and 4K video export.

Of course, this doesn’t mean 8GB has become equivalent to 16GB. Memory capacity still limits how much data and how many applications a computer can keep readily available. However, the results highlight why processor performance, memory management, and application efficiency all contribute to the overall experience.

Pureinfotech’s Take

I think this is one of the more important directions Microsoft can take with Windows 11. An otherwise capable computer shouldn’t feel sluggish simply because you’re running a few apps, keeping several browser tabs open, and switching between documents.

Microsoft’s work on memory compression, background tasks, and application efficiency is a meaningful step. It’s also especially relevant as memory prices put additional pressure on computer costs. As a result, using existing RAM more efficiently could help consumers get more out of their computers without spending more on hardware upgrades.

However, improving Windows 11 for 8GB devices shouldn’t become an excuse to keep selling computers with limited memory as everyday workloads continue to demand more resources. Microsoft’s performance claims are promising, but real-world results will determine how much users benefit.

What I find most encouraging is the company’s roadmap involving WinUI 3, shared app components, and hardware memory reservations. Windows doesn’t necessarily need more features right now. It needs to make the features and apps people already use faster, lighter, and more dependable.
