Windows 11 is now up to 20% more responsive on 8GB PCs, Microsoft says

The skim

• Microsoft says Windows 11 PCs with 8GB of RAM are now up to 20% more responsive, and finished one heavy multitasking test up to 40% faster than with January's builds.
• The biggest change: Windows can keep up to 2GB more of your active data in memory instead of moving it to slower storage, so apps and tabs you left open are less likely to reload.
• To get it, update to Windows 11 version 26H2, build 26300.9818 or later, and keep Edge, Microsoft 365 and Teams up to date.

What happened

In a Windows Experience Blog post on Nov. 3, Windows chief Pavan Davuluri wrote: "On 8 GB PCs, Windows is now up to 20% more responsive, and multitasking is up to 40% faster in our lab test."

Microsoft says the gains come from three places:

• Smarter memory compression. Windows now keeps up to 2GB more active data in RAM instead of paging it to the drive. Microsoft's analogy: memory is your desk, the drive is a drawer, and going to the drawer is what makes a tab reload.
• Faster everyday clicks. Opening Start, search, right-click menus, Settings, Snipping Tool and File Explorer responds up to 20% faster than with the January 2026 update, because Windows briefly prioritizes what you asked for and backs off background work such as search indexing.
• Leaner apps. Across Windows, Edge and Microsoft 365, Microsoft says committed-memory growth fell by up to 900MB in its multitasking tests, including 360MB from Word, PowerPoint, Excel and Outlook. On PCs with 8GB or less, Widgets now loads only when you open it (about 200MB saved), and Edge puts inactive tabs to sleep after 15 minutes instead of two hours.

Read the footnotes

The 40% figure comes from a single lab scenario: an 8GB HP OmniBook 3 with a Snapdragon X Plus chip opening 20 Edge tabs, a 4K video, large Office files, Outlook and File Explorer one after another. Microsoft's own footnote says the result is "specific to this scenario and configuration and are not a benchmark." Windows Latest points out that both builds in that test are earlier 25H2 builds, so part of the gain was already shipping before 26H2. The 20% responsiveness figure is based on telemetry from 8GB PCs.

Why it matters

8GB laptops have made a comeback this year, which Tom's Hardware ties to a global component shortage as AI demand pushes memory prices up. Microsoft is leaning into it: the same post promotes 8GB Windows 11 PCs as holiday buys. If you already own one, this is a free speedup worth installing. Microsoft still says heavy work such as 3D modeling, advanced video editing or large data processing benefits from 16GB or more.

How to get it

1. Open Settings > Windows Update.
2. Turn on Get the latest updates as soon as they're available.
3. Select Check for updates and install what's offered. You need Windows 11 version 26H2, build 26300.9818 or later.
4. Update Edge, Microsoft 365 and Teams too. Microsoft says some improvements arrive through app updates or the Microsoft Store.
