How To Fix Microsoft Edge High Memory Usage on Windows 11

Microsoft Edge has come a long way since the old Internet Explorer days. With its Chromium engine, faster performance, better tab management, and native Windows integration, Edge has become the daily browser for millions of users. However, like any modern browser, Edge sometimes suffers from high memory (RAM) usage, especially when multiple tabs, extensions, or background processes are running at once.

If you’re here reading about Edge’s high memory usage, we’re guessing your Windows PC feels sluggish when browsing, your RAM usage spikes when many tabs are open, or maybe your laptop’s fans start ramping up out of nowhere. Well, you’re in luck! In this in-depth guide, we’ll walk you through why Microsoft Edge may be using too much memory and provide some of the most effective methods to fix the issue. With the right optimizations, you can enjoy smooth performance again.

Why Does Microsoft Edge Use So Much Memory?

Before jumping into the fixes, it’s helpful to understand why Edge uses a significant amount of RAM. Modern browsers rely on multiple processes for better performance, isolation, and security. Edge is no exception.

Some common reasons behind high memory usage include:

• Too many tabs open at once
• Multiple extensions running in the background
• Tracking prevention and security processes
• Heavy web pages or poorly optimized websites
• Hardware acceleration conflicts
• Sleeping Tabs feature misconfigured
• Browser cache buildup
• Background system processes like Edge WebView2

Fix Microsoft Edge High Memory Usage on Windows

Below, we’ve compiled a list of reliable and effective fixes based on user reports, Microsoft recommendations, and performance optimization best practices. Follow them one by one and check what works best for your system.

1. Enable Sleeping Tabs in Microsoft Edge

Sleeping Tabs is one of Edge’s most powerful memory-saving features. It automatically “sleeps” inactive tabs, freeing up RAM while keeping your work intact.

1. Open Microsoft Edge.
2. Click the three-dot menu in the top right.
3. Select Settings.
4. Go to System and performance.
5. Turn on Save resources with sleeping tabs.
6. Set Put inactive tabs to sleep after to 5 minutes or less.
7. Under Never put these sites to sleep, add essential sites you always want active.

This alone can reduce RAM usage drastically, especially if you keep many tabs open.

2. Use the Browser Task Manager to Identify Heavy Tabs and Extensions

Edge includes a built-in Task Manager to help you pinpoint which tabs or processes are eating memory.

1. Press Shift + Esc inside Edge.
2. The Edge Task Manager will open.
3. Check the Memory column to identify heavy:
   • Tabs
   • Extensions
   • Background processes
4. Close or disable anything that’s consuming too much RAM.

This is one of the quickest ways to regain control over Edge’s memory use.

3. Disable or Remove Unnecessary Extensions

Extensions are great—but too many of them can significantly increase memory usage.

1. Click the three-dot menu → Extensions.
2. Review your list of installed extensions.
3. Disable the ones you don’t use frequently.
4. Remove the ones you no longer need.

Some extensions run background processes even when you aren’t actively using them, so trimming your list can immediately reduce RAM use.

4. Clear Cache and Browsing Data

Edge stores cached files to speed up browsing, but over time this cache grows and may cause performance issues.

1. Open Settings → Privacy, search, and services.
2. Under Clear browsing data, click Choose what to clear.
3. Select:
   • Cached images and files
   • Cookies (optional)
4. Click Clear now.

A cleaned-up browser often uses less memory and launches faster.

5. Disable Startup Boost (If You Don’t Need It)

Startup Boost keeps Edge running in the background to help it launch faster, but this consumes memory.

1. Go to Settings → System and performance.
2. Toggle Startup Boost OFF.

If you don’t mind Edge launching slightly slower, this can free up several hundred MB of RAM.

6. Turn Off Hardware Acceleration

Hardware acceleration can help performance, but it can also cause memory spikes or compatibility issues on some systems.

1. Open Settings → System and performance.
2. Toggle Use hardware acceleration when available OFF.
3. Restart Edge.

If memory usage drops, keep it off. Otherwise, turn it back on.

7. Reset Edge Settings to Default

If memory usage issues started recently, corrupted settings or flags may be the culprit.

1. Go to Settings → Reset settings.
2. Click Restore settings to their default values.
3. Confirm with Reset.

This resets features and flags but keeps your bookmarks and saved passwords.

8. Update Edge to the Latest Version

Many memory leak issues are fixed through updates.

1. Click the three-dot menu.
2. Go to Help and feedback → About Microsoft Edge.
3. Edge will automatically check for updates.

Once updated, restart the browser.

9. Scan Your System for Malware

Some malware disguises itself as browser processes and causes high memory usage.

1. Open Windows Security from Settings.
2. Go to Virus & threat protection.
3. Click Quick scan.
4. If needed, run a Full scan.

Removing malware often improves system and browser performance instantly.

10. Disable Edge from Preloading Web Pages

Edge preloads certain pages (especially Bing and Microsoft services) to speed things up, but this increases memory consumption.

1. Open Settings → Privacy, search, and services.
2. Scroll to Preload certain pages.
3. Toggle it OFF.

Wrapping Up

And that brings us to the end of our comprehensive guide on how to fix Microsoft Edge’s high memory usage on Windows. While it’s normal for modern browsers to use considerable RAM, excessive or constant spikes can slow down your PC. Thankfully, with features like Sleeping Tabs, built-in Task Manager, and a few smart optimizations, you can significantly reduce Edge’s memory footprint and enjoy smoother performance.
