Microsoft says its latest Windows 11 memory changes can help an 8 GB PC keep more apps and browser tabs ready to use. The company’s November 3 guidance points to Windows 11 version 26H2, build 26300.9818 or later. Some changes also require newer versions of Microsoft’s apps, so a current Windows build is one part of the check.
Check your Windows build and app versions
Open Settings, then System, then About. Under Windows specifications, compare the version and OS build with Microsoft’s target. The same page shows installed RAM under device specifications. Microsoft’s Windows release history lists build 26300.9818 as the October 28 release for version 26H2. The November 3 post explains which build to look for. October 28 is the date Microsoft lists for that specific build.
If your PC is behind, open Settings, then Windows Update, and select Check for updates. Microsoft also points to the option to get the latest updates as soon as they’re available. Rollout timing can vary by device and region. If you use a PC managed by your employer or school, its IT policy can determine when feature updates are offered.
Check your apps separately. Microsoft’s claim that Edge can open faster through Start or a link requires Edge version 150 or later along with the Windows build above. To find the installed version, open About Microsoft Edge in the browser’s settings. The company also calls for keeping Microsoft 365 and Teams current. An up-to-date copy of Edge does not tell you which Teams or Office changes your PC has received.
What Microsoft measured
The company’s headline figures refer to two different tests. The improvement of up to 20 percent came from measuring how quickly features such as Start, Search and File Explorer respond on 8 GB systems. The claim of up to 40 percent faster multitasking came from a lab test on one HP OmniBook 3 with a Snapdragon X Plus processor. The workflow opened 20 Edge tabs, a 4K video, large Office files, Outlook and File Explorer, keeping each open as the test progressed.
The Verge’s reporting describes how improved compression can leave more data in RAM instead of sending it to slower storage. Microsoft also says Widgets on PCs with 8 GB or less waits until you open it, and inactive Edge tabs now sleep after 15 minutes by default. These changes address different sources of memory use. The tab setting is relevant if you keep a browser open all day, while the Windows responsiveness figures cover specific system actions.
Decide whether your 8 GB PC still works for you
After updating, try the workload you actually use. Someone who works in a few browser tabs and a document might notice whether switching between them causes reloads. Someone who keeps a video call, a spreadsheet and dozens of tabs open at once can check whether those tasks run comfortably together. Task Manager can show how much memory is in use, but Microsoft notes that a high reading on its own does not establish a problem. Look for slowdowns or reloads during the work you need to get done.
Microsoft says more memory can help with demanding work such as advanced video editing, 3D modeling and large data jobs. If you’re shopping for a replacement, compare the processor and memory as well as the price. Microsoft’s commissioned comparison used different generations of Dell XPS 13 laptops. It cannot isolate what the same PC would gain from moving from 8 GB to 16 GB. The build check gives you a way to judge your existing machine before spending money on a different one.
