If Microsoft Edge is using too much memory on your Windows 11 PC, it can slow down your computer and cause other programs to lag. High memory usage often happens when many tabs are open, extensions consume resources, or certain features are enabled. Luckily, there are easy fixes like enabling Efficiency Mode, turning on sleeping tabs, disabling hardware acceleration, and adjusting resource controls that can help reduce Edge’s memory use and make your PC faster. In this blog, you’ll learn step-by-step methods to fix high memory usage by Microsoft Edge on Windows 11 and improve your browsing experience.
🛠 How to Fix High Memory Usage in Edge
1. Enable Sleeping Tabs
Edge has a built-in “Sleeping Tabs” feature that helps free up memory by putting inactive tabs to sleep.
- Open Settings in Edge.
- Go to System and performance.
- Turn on “Save resources with sleeping tabs”.
- Adjust the timeout (how long a tab must be inactive before sleeping) to a value that balances performance and responsiveness.
This ensures inactive tabs don’t continue consuming memory.
2. Limit Browser Pre-Loading and Background Tasks
Edge may pre-load tabs or run background tasks that eat up resources.
- In Edge settings under System and performance, disable:
- “Startup boost” – this helps Edge start faster, but uses memory in the background.
- “Continue running background extensions when Microsoft Edge is closed” – turning this off prevents extensions from running all the time.
3. Remove or Disable Unnecessary Extensions
Extensions can significantly increase memory usage.
- Type
edge://extensions/in the address bar to open the Extensions page. - Review installed extensions.
- Disable or remove any that you don’t need or rarely use.
- Restart Edge and monitor memory usage again.
4. Clear Browsing Data & Cache
A bloated browser cache can use a lot of memory.
- In Edge, go to Settings → Privacy, search, and services.
- Under Clear browsing data, click Choose what to clear.
- Select options like Cached images and files, Cookies and other site data, and History.
- Click Clear now.
Clearing this data periodically prevents cache buildup and frees memory.
5. Use Efficiency Mode
Efficiency Mode is designed to reduce resource usage.
- In Edge’s Settings → System and performance, enable Efficiency mode.
- Optionally, set a specific RAM threshold at which Efficiency Mode turns on (for example, when RAM usage exceeds 70%).
This dynamically reduces resource usage when Edge gets too heavy.
6. Update Edge to the Latest Version
Memory leaks or performance issues may be fixed in recent updates.
- Click the three-dot menu → Help and feedback → About Microsoft Edge.
- Edge will check for updates and install if any are available.
- After updating, restart Edge to apply changes.
7. Use Task Manager to Identify Problem Tabs
You can use Edge’s built-in task manager to see which tab or process is using the most memory.
- Press Shift + Esc inside Edge to open the browser’s Task Manager.
- Sort by Memory usage.
- Identify resource-heavy tabs or extensions.
- Right-click and choose End process for any unnecessary one.
