How to Free Up RAM in Windows 10

Share If You Find This Post Helpful!

In the digital age, our lives revolve around technology, and for many of us, that means relying on our trusty Windows 10 computers day in and day out. However, as we load our machines with applications, files, and web browsers, we often find ourselves facing a common issue – a sluggish computer due to limited available RAM (Random Access Memory). But fret not! In this comprehensive guide, we’ll explore the various strategies to free up RAM in Windows 10, ultimately boosting your PC’s performance. So, let’s dive in.

Understanding RAM

Before we delve into the techniques, let’s briefly understand what RAM is. RAM is your computer’s short-term memory, where it stores data that is actively being used. When RAM becomes congested with too many open applications, your computer may slow down. Here’s how you can optimize it:

1. Close Unnecessary Background Apps

One of the simplest ways to free up RAM is to close unnecessary background applications. Windows 10 often keeps apps running in the background, using up valuable resources. To do this:

  • Press Ctrl + Shift + Esc to open the Task Manager.
  • Navigate to the “Processes” tab.
  • Select any unwanted apps and click “End Task.”

2. Manage Startup Programs

Your computer might be loading too many programs at startup, which can hog RAM. To manage startup programs:

  • Press Ctrl + Shift + Esc to open the Task Manager.
  • Go to the “Startup” tab.
  • Disable programs that you don’t need to launch at startup.

3. Utilize the Windows Memory Diagnostic Tool

Windows 10 offers a built-in tool to check for memory problems. To use it:

  • Type “Windows Memory Diagnostic” into the search bar.
  • Click “Restart now and check for problems.”

4. Adjust Visual Effects

Windows 10 has various visual effects that can consume RAM. To optimize these settings:

  • Type “Performance” in the search bar and select “Adjust the appearance and performance of Windows.”
  • Choose “Adjust for best performance” to disable visual effects.

Advanced Techniques

For those looking to take their RAM optimization a step further, consider these advanced techniques:

5. Upgrade Your RAM

If your computer still struggles with RAM issues after implementing the above strategies, you might consider upgrading your RAM modules. Adding more RAM can significantly enhance your PC’s performance.

6. Use ReadyBoost

Windows 10 allows you to use external USB drives as additional RAM using the ReadyBoost feature. To enable it:

  • Insert a USB drive.
  • Right-click on the drive in File Explorer, go to “Properties,” and select the “ReadyBoost” tab.
  • Choose “Use this device” and adjust the slider to allocate space.

7. Optimize Virtual Memory

You can optimize your virtual memory settings to free up physical RAM. Here’s how:

  • Type “Performance” in the search bar and select “Adjust the appearance and performance of Windows.”
  • Go to the “Advanced” tab and click “Change” under Virtual Memory.
  • Uncheck “Automatically manage paging file size for all drives” and set a custom size.


In conclusion, a slow computer due to low RAM doesn’t have to be a persistent issue. By following these strategies, you can free up RAM in Windows 10 and enjoy a smoother, more responsive PC experience. Remember that regular maintenance and optimization are key to keeping your computer running at its best.
