Microsoft announced on November 3 a Windows 11 update aimed at PCs with 8GB of RAM. The company says Windows is now up to 20 percent more responsive and multitasking is up to 40 percent faster on such machines, according to The Verge. The figures come from Microsoft's own lab tests and compare against the January 2026 version of Windows 11.
Key facts
- Windows can keep up to 2GB more active data in memory through tuned compression, instead of moving it to slower storage.
- Committed-memory growth across Windows, Edge and Microsoft 365 apps drops by up to 900MB; Word, PowerPoint, Excel and Outlook account for 360MB of that.
- Widgets no longer load on 8GB PCs until opened (about 200MB saved), and inactive Edge tabs sleep after 15 minutes.
- Edge opens up to 33% faster, and Teams turns on Efficiency Mode by default on 8GB PCs, improving launch time by up to 20%.
- The changes require Windows 11 26H2, build 26300.9818 or later, per ZDNET.
How Microsoft measured it
The 20 percent responsiveness claim covers actions such as opening Start, searching, right-clicking, opening Settings, using the Snipping Tool and opening File Explorer, according to Tom's Hardware. Microsoft says it gets there partly by backing off background work such as search indexing while the user is active.
The 40 percent multitasking figure rests on one demanding workflow: 20 Edge tabs, a 4K video, large Word, PowerPoint and Excel files, Outlook and File Explorer opened in sequence. ZDNET reports that Microsoft ran this on the same 8GB PC with the current and January 2026 builds. Tom's Hardware notes the tests were internal and run in favorable conditions.
Microsoft also said it validates fixes across more than 20,000 PCs in its labs, including current 8GB models, using high-speed cameras to time on-screen results.
Why it matters
The update lands amid a memory shortage driven by AI demand. Digital Trends notes that RAM costs have surged, that Gartner has warned the sub-$500 PC segment could disappear by 2028, and that Apple's MacBook Neo adds pressure on Windows makers. XDA reports Microsoft began talking more about memory efficiency after the $600 MacBook Neo, which has 8GB of RAM, launched.
Shipping 8GB machines helps manufacturers hold prices down, but only if the operating system leaves enough memory for users. Microsoft still recommends 16GB or more for heavier work, a point Engadget also makes. Hardware matters too: Microsoft found a 2026 Dell XPS 13 with 8GB delivered 94% faster multi-core CPU performance than a 2021 8GB model, and matched a 2021 16GB system in some measures.
What to watch next
Microsoft says further work is coming over the next few months. Memory compression is to become smarter and more efficient, and Windows features such as Search and Widgets will share a single web engine. File Explorer and Notepad, as WinUI 3 apps, are to be redesigned to use less memory and open faster.
Microsoft is also working with PC makers and chipmakers to reduce the memory a PC reserves for its hardware, which would free more for Windows. Independent testing will show whether the lab gains hold up on real 8GB hardware.
