Windows 11 update makes 8 GB PCs up to 40% faster

Microsoft released a Windows 11 update today that reshapes how the operating system uses memory on computers with 8 GB of RAM. The change promises up to a 20 percent boost in responsiveness and multitasking that can feel up to 40 percent faster in lab tests. The update arrives as part of a broader effort to make the platform run smoother on modest‑memory machines.

How the update works

According to The Verge, the core of the improvement is a more aggressive memory‑compression algorithm. By compressing data in RAM, Windows can now keep about 2 GB more of active information in memory instead of moving it to slower storage. This reduces the need for the virtual‑memory paging file, which historically slows apps when data is swapped to disk.

The update also trims what Microsoft calls “committed‑memory growth” by up to 900 MB across the system. Specific savings come from Microsoft 365 apps: Word, PowerPoint, Excel, and Outlook together free roughly 360 MB of RAM. Windows 11 no longer loads widgets on a PC with 8 GB of RAM until you open the widgets panel, saving around 200 MB. In Microsoft Edge, inactive tabs enter a sleep state after 15 minutes, further lowering memory pressure.

These changes are delivered through a single Windows update, so users do not need to reinstall any software. The improvements apply automatically to supported builds once the update is installed.

What the numbers mean for everyday use

The lab figures quoted by Windows chief Pavan Davuluri translate into noticeable differences for most users. When you switch between applications or browser tabs, Windows will spend less time reloading content because more of your recent data stays in RAM. This can feel like faster app launches, smoother scrolling, and reduced lag when you have several programs open.

For small‑business owners who rely on Microsoft Office daily, the RAM savings in Word, Excel, PowerPoint, and Outlook mean those apps will stay snappier even when you keep many documents open. Likewise, the Edge tab‑sleep feature helps keep the browser responsive while you work on other tasks, without manually closing tabs.

If your machine has exactly 8 GB of RAM, you are likely to see the biggest impact, as the system previously had to rely more heavily on paging. Users with more than 8 GB will still benefit from the efficiency gains, but the relative speed boost may be less dramatic.

Practical steps to get the most out of the update

• Open Settings → Windows Update and install the latest optional update for Windows 11.
• Restart your computer after the update finishes to ensure all changes take effect.
• Review startup programs in Task Manager → Startup and disable anything you don’t need each day.
• In Edge, keep the default tab‑sleep timer (15 minutes) or adjust it in Settings → System and performance if you prefer a shorter or longer interval.
• Monitor memory usage with Task Manager → Performance to see the reduction in RAM consumption after the update.
• If you still experience slowdown, consider adding more RAM; the update is designed to work best with 8 GB or more.
• For businesses that manage many PCs, use Microsoft Endpoint Manager to push the update across the fleet and verify compliance.

What’s coming next

Microsoft says the memory‑compression engine will continue to get smarter over the next few months, allowing it to store even more data in RAM without sacrificing speed. The company also plans to unify the web engine used by widgets and search, which should further reduce duplicate memory use.

Additionally, Microsoft is working with PC manufacturers and chip makers to reserve less memory for hardware functions, freeing more for the operating system. Those collaborations could make low‑end PCs feel even more capable without hardware upgrades.

Overall, the update represents a clear step toward making Windows 11 a more viable platform for budget‑friendly hardware, which is especially relevant for small businesses, nonprofits, and public‑sector teams that often run on older or lower‑spec machines.
