Summary

This guide helps you troubleshoot and resolve: How to Fix Slow Windows 11 Performance Caused by High RAM Usage from Too Many Browser Tabs and Background Apps. Follow the steps below to fix the issue.

Common Causes

If your Windows 11 computer feels sluggish, freezes frequently, or takes a long time to respond, high RAM usage may be the cause. This often happens when too many browser tabs are open at once or when multiple applications run in the background. This guide will help you identify what is consuming your memory and reduce the load to restore normal system performance.

Quick Fix Steps

1. Close any browser tabs you are not actively using.
2. Restart your computer to clear temporary memory usage.
3. Close unnecessary applications running in the system tray.
4. Open Task Manager to identify and end high-memory processes.

Detailed Instructions

1. Press Ctrl + Shift + Esc to open Task Manager.
2. If you see a simplified view, select More details at the bottom of the window.
3. Click the Processes tab.
4. Click the Memory column header to sort applications by memory usage, highest to lowest.
5. Look for web browsers (such as Microsoft Edge or Google Chrome) with many open tabs, or background applications you do not recognise.

2. Close Unnecessary Browser Tabs

1. Open your web browser.
2. Review your open tabs and close any you are not currently using by selecting the X on the tab.
3. If you need to keep pages for later, consider bookmarking them instead of leaving them open.
4. Restart the browser to release memory that may still be held by closed tabs.

2. Select the Show hidden icons arrow (the small upward-pointing chevron).

4. Common examples include cloud storage clients, messaging apps, and media players.

4. Disable Startup Apps

1. Open Task Manager using Ctrl + Shift + Esc.
2. Select the Startup apps tab from the left-hand menu.
3. Review the list of applications that launch when Windows starts.
4. Right-click any non-essential application and select Disable.
5. Restart your computer for changes to take effect.

5. Restart Your Computer

1. Select the Start button.
2. Select the Power button.
3. Choose Restart.
4. Allow Windows to fully reboot before reopening your applications.

Troubleshooting

Performance Does Not Improve

• Ensure Windows 11 is fully updated. Go to Settings > Windows Update and select Check for updates.
• Check available storage space. Open File Explorer, select This PC, and confirm your main drive has several gigabytes of free space.
• Run a malware scan using your installed security software.

Computer Continues to Freeze or Crash

• If your system becomes unresponsive, press and hold the physical power button for 10 seconds to force a shutdown, then restart normally.
• If applications are freezing or crashing, refer to our guide on Applications freezing or crashing.
• If you encounter a blue screen, follow the steps in Blue screen of death (BSOD) - restart steps.

Browser-Specific Issues

• If web pages are slow to load or fail to open, see Browser not loading pages.
• Try opening your browser in private or incognito mode to determine if an extension is causing high memory usage.
