High memory usage on Windows 11 can slow down your computer, making it frustrating to use. This guide will show you how to identify and fix high memory usage on Windows 11 to keep your system running smoothly. By following these steps, you can manage your computer’s resources effectively and improve its performance.
How to Fix High Memory Usage Windows 11
The following steps will help you address high memory usage on your Windows 11 computer. We will go through identifying the issue, closing unnecessary programs, adjusting settings, and running system maintenance tasks.
Step 1: Open Task Manager
Press Ctrl+Shift+Esc to open Task Manager.
In Task Manager, you can see which applications and processes are using up your memory. This will help you identify any programs that are hogging your system’s resources.
Step 2: Check Memory Usage
Go to the "Performance" tab and click on "Memory" to see a detailed breakdown of your memory usage.
The Performance tab will give you a visual representation of how much memory is being used and by what. If you see any programs using more memory than expected, take note of them.
Step 3: End High Memory Processes
Right-click on any high-memory process and select "End task."
Be cautious when ending tasks, as some are vital for Windows to run correctly. Focus on user applications rather than system processes.
Step 4: Disable Startup Programs
Go to the "Startup" tab in Task Manager and disable unnecessary startup programs.
Disabling startup programs reduces the number of applications running in the background. This can significantly lower memory usage when you boot up your computer.
Step 5: Adjust Virtual Memory
Open System Properties, go to the Advanced tab, and click on "Settings" under Performance. Then, click on "Advanced" and "Change" under Virtual Memory.
Adjusting virtual memory settings can help manage the memory load better. Customizing this can free up physical RAM for more critical tasks.
Step 6: Update Windows and Drivers
Go to Settings > Windows Update and ensure your system and drivers are up to date.
Updating your system can often fix bugs that cause high memory usage. Regular updates ensure your computer has the latest patches and improvements.
Step 7: Run Disk Cleanup
Search for "Disk Cleanup" in the Start menu, run the tool, and select the files you want to remove.
Disk Cleanup can free up space and remove temporary files that can slow down your system. It’s an easy and effective way to maintain your computer.
After completing these steps, your computer should run more smoothly, and you should notice a decrease in memory usage. Regular maintenance and monitoring can prevent high memory usage from becoming a recurring issue.
