Microsoft is making the case that Windows 11 can run comfortably on PCs with 8GB of memory again, and it has released a comparison video to back up that claim.
According to a report by Windows Latest, the company says systems running Windows 11 26H2 or later can be up to 40% more responsive, with the biggest gains showing up on lower-memory machines. Most of the underlying changes are already shipping.
A Shift in Messaging on Memory
For roughly two years, the prevailing guidance around Windows PCs pushed buyers toward 16GB of RAM for everyday use and 32GB for serious gaming. That message is now softening.
With memory prices high, Microsoft has gone back to selling PCs with 8GB of RAM, and its hardware partners are doing the same. Those devices are meant to compete with Apple's MacBook Neo, which has generally been seen as handling limited resources more gracefully than Windows 11.
Inside the Side-by-Side Test
In the demonstration, Microsoft used two PCs, each with 8GB of RAM. One ran the January 2026 Windows 11 update, released before the performance commitments the company made in March 2026. The other ran the 26H2 release, also known as the October 2026 Update.
Both machines performed an identical workload: opening 20 Edge tabs populated with fictional brand sites, playing a 4K video, and launching File Explorer, the right-click menu, Word, PowerPoint, Excel and Outlook.
The newer build completed the sequence first. The older one frequently stalled on blank or loading windows while the updated machine had already moved to the next app. Microsoft's fine print notes the footage was sped up and compares builds 26200.7623 and 26200.9445.
Where the 40% Figure Comes From
Microsoft's responsiveness claim is based on response times for core interface elements, including Search, the Start menu, right-click menus, Settings, the Snipping Tool and File Explorer, measured on 8GB PCs.
For that comparison, the company pitted Windows 11 Build 26300.9550 (26H2) against Build 26200.7628 (25H2). Microsoft says gains can exceed 40% on certain configurations, though results will vary by device, setup and usage.
Windows Latest suggests the improvements are likely tied to Low Latency Profile, a feature that briefly boosts CPU performance to make the system feel snappier.
Lower Memory Use Across Everyday Apps
Alongside speed, Microsoft is highlighting memory savings. The company says common apps now use up to 900MB less committed memory than they did in January 2026, with the gap widening as more apps are opened in the demo.
Microsoft says the figure reflects changes in system-committed memory measured from a baseline to a final state while multitasking with Edge, Office, Outlook and Teams. On a machine with only 8GB available, freeing close to a gigabyte is a meaningful difference.
Caveats for Users Expecting Big Gains
The improvements are not guaranteed to look the same on every PC. Microsoft notes that "rollout timing and availability may vary by device and region," so some users may not have the changes yet.
Machines with more memory will see less dramatic changes, since the work mainly targets low-RAM bottlenecks. Windows Latest also cautions that PCs with weaker processors may not benefit as much, because features like Low Latency Profile depend on CPU headroom.
What It Means for Buyers and PC Makers
For PC manufacturers, a leaner Windows makes 8GB configurations more viable at a time when memory costs are squeezing margins and pricing.
For buyers, the update offers a reason to revisit budget machines that previously felt sluggish. The real test will be whether everyday users on varied hardware see the same gains Microsoft showed under controlled conditions.
