Windows 11 8GB RAM Improvements: What Microsoft’s 20% and 2GB Claims Really Mean

Microsoft does have numbers to show. They just measure narrower things than the headlines suggest, and the two Microsoft announcements behind Gizmodo's piece need separating first.

Correcting the record: who said what, and when​

Gizmodo says Windows chief Pavan Davuluri wrote a blog post "published Tuesday" claiming Windows 11 would be up to 20% faster on PCs with limited memory. That attribution checks out: Davuluri published a Windows Experience Blog post on Tuesday, November 3, 2026, making the 20% claim alongside a multitasking claim (see below). It is a separate, later announcement from the Windows Experience Blog post dated October 15, 2026, written by Navjot Virk, Microsoft's corporate vice president of Windows experiences, which covered overlapping memory figures. Several outlets covered that post the same week. On October 15, 2026, Microsoft announced memory changes for Windows 11.

Davuluri is still part of the story. Windows Latest reported that on the Inside Windows podcast he called memory "top of mind for us right now in the industry," because memory prices are rising across the board.

Gizmodo also says Microsoft claimed multitasking would be "up to 40% faster" based on internal lab benchmarks. That figure is in Microsoft's November 3 post, with a published methodology: a lab test on an HP OmniBook 3 with 8GB of RAM and a Snapdragon X Plus 8-core processor, running 20 Edge tabs, a 4K video, large Word, PowerPoint and Excel files, Outlook and File Explorer, comparing builds 26200.7623 and 26200.9445, with Microsoft noting the result is specific to that scenario and "not a benchmark." The October 15 post is a separate announcement and does not carry the 40% figure.

Section summary: The October announcement came from Navjot Virk on October 15, and a further announcement came from Pavan Davuluri on November 3. The 20% figure is real, and the 40% figure is Microsoft's published lab-test result, with the methodology above.

Microsoft's three numbers, and what each one measures​

Microsoft's post gives three figures for performance and memory. They measure different things, so they shouldn't be blended into one "Windows is 20% leaner" headline.

Microsoft's footnotes say actual results vary by device, configuration and usage, and that rollout timing can vary by device and region.

The 2GB figure is the one most often misread. VideoCardz explained it well: this does not mean Windows suddenly requires 2GB less RAM, but rather that improved memory management reduces the need to swap active data to storage. In plain terms, Windows is better at keeping your open work in fast memory. That doesn't mean Task Manager will show 2GB less in use.

The Widgets change is smaller but easy to understand. Computers with 8GB of RAM or less will no longer load Windows Widgets before you actually open them, and Microsoft claims this can open up more than 200MB of memory for other apps and workloads. MakeUseOf noted that while the 200MB figure doesn't sound enormous, it can amount to roughly 2.5% of the physical memory available on an 8GB machine.

Section summary: Each number describes a different measurement. None of them promises your PC will feel 20% faster overall.

What Microsoft told Gizmodo about how the work is done​

The most detailed engineering claims come from Gizmodo's interviews. Microsoft's public blog post doesn't confirm them, so they're attributed to Gizmodo here.

• Changes at every level. Marcus Ash, Microsoft's VP of Windows design and research, told Gizmodo the work goes from the kernel through the scheduler and up to user apps such as File Explorer and web browsers.
• More compression before paging. Klaus Diaconu, a product manager for Windows fundamentals, told Gizmodo that Windows will compress memory more aggressively before falling back to the SSD. Gizmodo says this "3x compression" approach could save close to 2GB when memory runs short. That roughly matches Microsoft's public "up to 2GB more active data" claim, though the blog doesn't mention compression ratios.
• WinUI 3 instead of WebView2. According to Gizmodo, File Explorer, Notepad, Paint, Photos and the new Search are built with Microsoft's native WinUI 3 framework instead of WebView2, which runs app interfaces on embedded browser technology and uses more memory. Diaconu said not every app will switch, because some still need to display web content.
• One shared WebView2 for Office. Gizmodo reports that Microsoft wants all Office apps to share one WebView2 instance instead of each loading its own.
• Memory leaks and default apps. Diaconu described his team as "meticulous" about fixing memory leaks. Gizmodo also reports that Edge will put unused tabs to sleep after 15 minutes instead of the current two-hour default.

Some of this matches what Microsoft has said elsewhere. Windows Latest reported that in July, Microsoft made "Memory optimization for 8GB and above" an official focus area, along with a more efficient memory allocator and efficiency work across WinUI 3, Chromium and WebView2.

Section summary: Gizmodo's interviews describe deep changes to memory handling, compression and app frameworks. The general direction lines up with Microsoft's July roadmap, but the specific figures come only from those interviews.

Independent testing: encouraging, with caveats​

Windows Latest tested Windows 11 26H2 on an 8GB laptop and on a fresh 8GB virtual machine.

• The laptop (DDR4 RAM, SATA SSD, many apps installed) went from build 26200.9550 to build 26300.9550. After a restart, memory in use fell from about 5.0GB to 3.3GB, and available memory rose from 2.9GB to 4.6GB.
• The VM started on an October 2025 build (26200.6899) using about 4.1GB with no apps installed. After updating to build 26300.9711, it used roughly 2.8GB to 3.2GB.

The reviewer listed the limits himself. These are single machines, he ran no benchmark, and the VM skipped a whole year of updates, so 26H2 alone can't explain the drop. He also pointed out that his 1.7GB laptop saving is far more than the Widgets change could account for. And not everyone saw gains: Windows Latest noted that one 8GB PC owner reported no change at all, with RAM usage stuck at 96%.

One more catch from Windows Latest: Widgets saves memory partly because Microsoft separated the Discover/MSN feed from Widgets. If you open that feed, memory use climbs back toward where it was.

Windows Latest also explained that 26H2 is an enablement package sharing code with 24H2 and 25H2. Many of these improvements arrived gradually through monthly updates, and 26H2 is simply when more people noticed.

Section summary: Early tests show a real drop in idle memory on some 8GB machines. Results vary, and some of the improvement came from months of earlier updates.

How to check your own PC​

You don't have to rely on anyone's word for this. A quick check:

• Find your build. Press Win+R, type winver, and press Enter. Microsoft's figures are based on build 26300.9550.
• Restart, then wait. Let the PC sit idle for a few minutes after booting so startup tasks finish.
• Open Task Manager (Ctrl+Shift+Esc) and go to Performance > Memory. Write down In use, Available, Compressed and Committed. These are the same fields Windows Latest compared.
• Compare after updating. Do the same steps after the update, with the same startup apps.
• Test your real workload. Idle numbers are only part of the picture. Open your usual browser tabs and work apps and see whether switching between them stutters less.

If your numbers barely change, check your startup apps, browser extensions and any third-party tools running in the system tray. No operating-system optimization can rescue a startup list that loads a dozen updaters.

Section summary: Use winver and Task Manager to measure before and after, and judge by your daily workload, not just idle memory.

The other changes in the release​

The memory work is part of a larger Windows 11 update. Microsoft's October post says users can choose where the taskbar appears on screen, Widgets are being made "cleaner and quieter," and Windows Update should give more control over timing with fewer restarts. Microsoft also says the redesigned Photos app launches up to 20% faster, which is a separate, app-specific result. Gizmodo notes the movable taskbar may not be as freeform as Windows 10's.

The new Search, which can change settings such as dark mode or night light directly from the results, has a stated availability limit. Microsoft's post says it was available to Windows Insiders at announcement and would roll out more broadly later in the year. Gizmodo also notes that some of these features aren't yet available outside beta builds.

Why Microsoft is doing this now​

Rising memory prices explain the timing. Computerworld reported that due to the global memory shortage, 8 gigabytes has once again become the standard among computer manufacturers. Windows Latest pointed to examples including a Surface Laptop 13 starting at $949 with 8GB, and noted that Microsoft quietly removed support guidance recommending 32GB for gaming. Gizmodo makes the same point about Microsoft's Windows Learning Center.

Gizmodo argues that Microsoft needs a clearer way to tell buyers which PCs suit which tasks, and says the Copilot+ label has largely fallen out of use. That's an editorial argument, not a reported fact, but it's a reasonable one. Gizmodo's own estimate is that serious local-AI work needs at least 24GB. Even a much leaner Windows 11 won't change that.

The bottom line​

The direction is right, and the early evidence is real. Microsoft has concrete, build-specific claims, and at least one hands-on test showed a large drop in idle memory on an 8GB laptop. Readers should still keep these limits in mind:

• The 20% figure covers specific interface response times between two builds. It doesn't mean every task gets faster.
• The 2GB figure is about keeping data in RAM instead of paging it to storage. It isn't a 2GB cut in memory use.
• The 200MB Widgets saving applies only to PCs with 8GB or less, and it shrinks if you use the Discover feed.
• The 40% multitasking figure is Microsoft's published lab-test result (November 3 post, HP OmniBook 3 test described above), though it is specific to that scenario; Gizmodo's engineering details from its interviews remain interview-only and aren't in Microsoft's public announcement.

An 8GB PC is still an 8GB PC. Microsoft can make it waste less memory, but it can't make it a 16GB machine. For buyers with tight budgets right now, a Windows that wastes less memory still helps.

Correction (November 3, 2026): An earlier version of this article said Gizmodo had misattributed the 20% claim to a Pavan Davuluri blog post and that the 40% multitasking figure had no public support or published methodology. That was wrong: Davuluri published a Windows Experience Blog post on November 3, 2026, stating both figures, with footnoted lab-test methodology for the 40% result. The article has been corrected.
