How to reduce memory usage windows 11

Last Updated: Jan 19, 2024 by

Windows 11 is the latest operating system from Microsoft, and it comes with a sleek new design and improved performance. However, with all the new features and updates, it also requires more memory to run smoothly. This can be a problem for users with older or low-end devices. In this article, we will discuss How to reduce memory usage in windows 11 and optimize your system for better performance.

Why is Memory Usage Important?

Before we dive into the ways to reduce memory usage, let’s first understand why it is important. Memory, also known as RAM (Random Access Memory), is a crucial component of your computer. It is responsible for storing data and instructions that are currently in use by the operating system and applications.

When your computer runs out of memory, it starts using the hard drive as virtual memory, which is much slower and can cause your system to lag or freeze. This is why it is essential to manage your memory usage and optimize it for better performance.

Memory Allocation and Management

Memory allocation is the process of assigning memory to different applications and processes. The operating system manages this process and decides how much memory each application can use. However, sometimes, certain applications may use more memory than necessary, causing your system to slow down.

Memory management, on the other hand, is the process of monitoring and controlling the usage of memory. It ensures that memory is allocated efficiently and that there is enough free memory available for new applications.

Memory Usage Optimization

Memory usage optimization is the process of reducing the amount of memory used by your system and applications. This can help improve overall system performance and prevent your computer from running out of memory.

How to Reduce Memory Usage in Windows 11

Now that we understand the importance of memory usage, let’s look at some ways to reduce it in Windows 11.

1. Close Unnecessary Applications

The simplest way to reduce memory usage is to close any unnecessary applications. Many times, we tend to keep multiple applications open, even when we are not using them. This can use up a significant amount of memory, causing your system to slow down.

To close applications, right-click on the taskbar and select “Task Manager.” In the Processes tab, you can see all the applications and processes currently running on your system. Select the ones you want to close and click on “End Task.”

2. Disable Startup Programs

Many applications automatically start when you turn on your computer, using up valuable memory. To disable these startup programs, go to the Task Manager and click on the “Startup” tab. Here, you can see a list of all the programs that start when your computer boots up. Right-click on the ones you want to disable and select “Disable.”

3. Use the Windows Memory Diagnostic Tool

Windows 11 comes with a built-in Memory Diagnostic Tool that can help identify and fix any memory-related issues. To access this tool, go to the Start menu and search for “Windows Memory Diagnostic.” Click on the first result and select “Restart now and check for problems.”

The tool will run a series of tests and inform you if there are any issues with your memory. If it finds any problems, it will suggest solutions to fix them.

4. Adjust Virtual Memory Settings

As mentioned earlier, when your computer runs out of memory, it starts using the hard drive as virtual memory. By default, Windows automatically manages virtual memory, but you can adjust the settings to optimize it for better performance.

To do this, go to the Control Panel and search for “Performance.” Click on “Adjust the appearance and performance of Windows” and go to the “Advanced” tab. Here, click on “Change” under Virtual memory and uncheck the box that says “Automatically manage paging file size for all drives.” You can then manually adjust the virtual memory size for each drive.

5. Use a Memory Optimization Tool

There are many third-party memory optimization tools available that can help reduce memory usage and improve system performance. These tools work by freeing up memory that is not being used by applications and processes.

One such tool is CleanMyPC, which can scan your system for unnecessary files and processes and optimize your memory usage. It also has a feature called “Hibernation” that can free up even more memory by putting inactive applications into a hibernation state.

Best Practices for Managing Memory Usage

Apart from the methods mentioned above, here are some best practices for managing memory usage in Windows 11.

1. Keep Your System Updated

Microsoft regularly releases updates for Windows 11 that include bug fixes and performance improvements. Make sure to keep your system updated to ensure it is running smoothly and efficiently.

2. Use Lightweight Applications

Some applications are known to use a lot of memory, even when they are not in use. Try to use lightweight alternatives for these applications to reduce memory usage.

3. Add More Physical Memory

If you are constantly running out of memory, consider adding more physical memory to your system. This can significantly improve performance and prevent your system from slowing down.

4. Close Unused Browser Tabs

Web browsers are notorious for using up a lot of memory, especially when you have multiple tabs open. Make sure to close any unused tabs to free up memory.

5. Use a Memory Monitoring Tool

There are many memory monitoring tools available that can help you keep track of your memory usage. These tools can give you real-time information about which applications are using the most memory, allowing you to take action accordingly.


Managing memory usage is crucial for maintaining a smooth and efficient system. By following the methods and best practices mentioned in this article, you can reduce memory usage in Windows 11 and optimize your system for better performance. Remember to regularly monitor your memory usage and take action when necessary to ensure your system is running at its best.
