What actually changed for 8 GB Windows 11 PCs in the November update?

The desk analogy and what it means for your open tabs

RAM is your desk. Everything you are working on sits there within reach. When the desk fills up, the system moves less active items to a drawer — your drive — and fetches them back when you return. That trip to the drawer is what you feel as a pause when an old browser tab reloads.

The November update tunes how much Windows compresses, when it uses the drawer, and when it fetches data back, specifically for 8 GB machines.

The result: the system can now keep up to 2 GB more of your active data in memory instead of moving it to slower storage. An app or tab you left open is less likely to reload when you come back.

Interactions that used to lag

Opening Start and searching now respond up to 20 percent faster on 8 GB PCs compared with the January 2026 update. Right-clicking, opening Settings, and launching Snipping Tool also improved by a similar margin. File Explorer joins the list of faster interactions.

The OS achieves this by briefly prioritizing the work you just asked for and backing off background tasks such as search indexing while you are active. The first few minutes after a restart from an update are a good test: setup work continues without making you wait to open your browser.

Click a link or open Edge from Start and the browser is often already running in the background. Windows now connects to it directly instead of searching for it first, which can open Edge up to 33 percent faster. This requires Windows 11 build 26300.9818 or later and Microsoft Edge 150 or later.

Multitasking pressure test

Microsoft ran a demanding scenario on the same 8 GB HP OmniBook 3 with a Snapdragon X Plus 8-Core processor. The test opened 20 Edge tabs, a 4K video, large Word, PowerPoint and Excel files, Outlook, and File Explorer one after another and kept everything open. With the new build the workflow completed up to 40 percent faster than on the January 2026 build.

Results are specific to this scenario and configuration and are not a general benchmark. Actual performance varies by device, configuration, files, active and background workloads, and other factors.

Where the memory savings come from

Across Windows, Microsoft Edge, and Microsoft 365 apps, committed-memory growth during multitasking dropped by up to 900 MB on 8 GB PCs. A significant part comes from Microsoft 365 apps. Word and PowerPoint together save memory thanks to more efficient ways of organizing and allocating memory that reduce management overhead. Excel and Outlook add further savings.

Widgets now loads only when you open it on PCs with 8 GB or less, reducing memory commitment by roughly 200 MB while closed. In Edge, inactive tabs go to sleep after 15 minutes by default, down from two hours, cutting the memory used by tabs you are not actively using.

WhatsApp is cited as an example of a third-party app seeing double-digit memory improvement in its Windows version. The platform changes enable other developers to see similar benefits.

New silicon changes the baseline

In commissioned third-party testing by Principled Technologies using Cinebench multi-thread performance, a 2026 8 GB Dell XPS 13 delivered up to 94 percent faster multi-core CPU performance than a 2021 8 GB model. The same 2026 8 GB PC performed about as well as a 2021 16 GB configuration across CPU performance, web browsing, AI-powered web tasks such as background blur and face detection, and 4K video export.

Memory still matters for heavier and highly multitasked workloads, but the results show why the complete PC — not memory capacity alone — shapes the experience. Performance varies by device configuration and other factors.

What comes next

Compression will get smarter and more efficient. Windows features and apps will share common parts instead of each carrying its own. Search and Widgets will share one web engine. OneDrive and Photos will share another, for memory savings across all four apps.

Apps built on WinUI 3 — including File Explorer, Notepad, Paint, and the new Windows search — are being designed to open faster and use less memory. Collaboration with PC makers and silicon partners aims to optimize how much memory the PC reserves for its hardware, leaving more available for Windows and your apps. Work with third-party developers continues to help their apps use memory more efficiently.

How to get the improvements

Update to Windows 11 version 26H2, build 26300.9818 or later. Go to Settings > Windows Update, turn on "Get the latest updates as soon as they're available," and select Check for updates. Keep Microsoft Edge, Microsoft 365, and Teams updated as well, since some improvements arrive through app updates or the Microsoft Store.

New 8 GB Windows 11 PCs start at $429 at Walmart as of November 2, 2026. Deals with savings of up to $200 each week run from November 2 through December 25 at select retailers including Best Buy and Microsoft.com, while supplies last. Pricing is determined by retailers and subject to change.
