How to fix low Virtual memory issues in Windows 11/10

Low Virtual Memory issues. If Windows slows down or crashes randomly when running demanding programs such as games, AutoCAD or Visual Studio, a system memory problem may be to blame. When the Windows operating system runs out of memory, it uses virtual memory to store the least used memory pages in a file called pagefile.sys, at which point you may receive the error message “Your computer does not have enough virtual memory”.

This is a very annoying problem. Here, you’ll learn how to increase your computer’s virtual memory and how to solve the problem of insufficient virtual memory in Windows 10/11.

What is Virtual Memory?

Virtual memory is the memory that helps the operating system to run resource-intensive applications. However, in Windows 10, virtual memory shortage can occur when Windows cannot access the pagefile.sys file. To resolve the Windows 10 “Too little virtual memory” error, follow the solutions below, but first find out why you are running out of virtual memory.

What Causes Running Low on Virtual Memory?

A virtual memory shortage error occurs when the virtual memory on a Windows computer is too small and the amount of memory needed by the program increases.

The operating system determines the size of the pagefile.sys file after calculating the amount of RAM installed on the computer. If your computer has 8 GB of physical RAM, the amount of virtual memory allocated by Windows is 2 GB on a 32-bit system and about 4 GB on a 64-bit system.

If you get an error message that the virtual memory in Windows 10 is too small, it means that the program you’re trying to run requires too many resources and the virtual memory can’t handle it. This is why it’s important to increase the amount of virtual memory in Windows 10. Here are instructions on how to do that:

How to Increase Virtual Memory in Windows 10?

To avoid a virtual memory shortage problem, it is important to set a larger virtual memory value. Therefore, first, eliminate the “Too little virtual memory” error by following the given instructions.

  • Press the Windows + R keys to open the Run dialog box.

  • Type sysdm.cpl to open the “System Properties” dialog box.
  • Next, go to the Advanced tab and click the Settings button on the Performance tab.
  • The “Performance Settings” window will open, then click on the “Advanced” tab.
  • Click the “Edit” button on the “Virtual Memory” tab.

  • Then click on the “Custom Size” radio button. Here, you can set a new initial and maximum size for the pagefile.sys file.
  • Click on OK, and in the next window, click on Apply and restart your computer.

The error “There is not enough free virtual memory on your computer” was resolved after increasing the virtual memory size.

What to do when Windows virtual memory is too low

Solution 1: Add More RAM

Pagefile.sys uses the system’s hard disk space to create virtual memory, which is much slower than real RAM. Therefore, increasing the RAM can eliminate the Windows 10 virtual memory error, which indicates insufficient virtual memory.

Solution 2: Disable Apps and Programs

Low memory in Windows 10 can also be caused by applications that consume all of the system’s memory. Therefore, we recommend disabling these applications to solve the problem of low virtual memory.

However, to do this, you must first identify the memory-consuming apps and programs that are installed on your PC/laptop.

To do this, follow the steps below:

  • Press Ctrl+Shift+ESC to launch and open the Task Manager.
  • Click on the Processes tab and select Memory to select programs that consume a lot of memory.

  • Right-click each program and click the Clear Tasks button.

That’s it; memory-consuming apps and programs will be disabled.

Solution 3: Clean Temporary Files & Folders

If you are a computer user, you should know that when you work on your computer or surf the Internet, a lot of unnecessary files accumulate, which affect the system memory and can cause errors in virtual memory.

Therefore, running the “Disk Cleanup” utility will remove unnecessary files and clear the system memory.

To run it, follow the instructions:

  • Launch the Disk Cleanup tool.
  • Select the disk to be cleaned; the utility will delete unnecessary files and show the free space.

  • In the Disk Cleanup dialog box, select Clean system files.
  • If necessary, select the disk to clean and click OK.
  • Now on the Disk Cleanup tab of the dialog box, select the check boxes next to the types of files you want to delete and click OK. Now, to delete data from a previous Windows installation, check the Previous Windows Installations check box.
  • Then in the message that appears, select Delete Files.
  • Now press Windows + E to open the file browser, select the deleted disk, and select Refresh.

Solution 4: Scan Your System for Virus Infection

Sometimes, malicious threats or virus programs are installed on the system unnoticed and start running in the background. This negatively affects the system and uses up all the free memory.

In this case, we recommend that you check your system for viruses or malware with a good antivirus program. If you don’t have third-party antivirus software installed, use the built-in Windows Defender or run a third-party virus removal tool such as SpyHunter.

Here are ways to debug virtual memory in Windows 10. Follow the given solutions one by one to increase virtual memory in Windows 10. Follow the solutions carefully. The given solutions do not only work for Windows 10 systems; users of other Windows versions can follow them as well.


How do I fix low virtual memory?

To fix low virtual memory issues, you can:

  • Increase the size of the virtual memory (paging file) in Windows settings.
  • Close unnecessary programs and processes to free up memory.
  • Upgrade your computer’s RAM if possible.
  • Optimize your system for better memory management.

Is less virtual memory better?

No, less virtual memory is not necessarily better. Virtual memory acts as a supplement to physical RAM, allowing the system to run more applications simultaneously. Insufficient virtual memory can lead to performance issues and system instability.

Does virtual memory increase RAM?

Virtual memory doesn’t directly increase the physical RAM installed on your system. Instead, it utilizes a portion of your hard drive space to simulate additional RAM. This allows your system to run more applications than it could with just physical RAM alone.

What is virtual memory for 4GB RAM?

With 4GB of RAM, virtual memory serves as a crucial extension to support the system’s operations and running applications. Typically, the virtual memory size for a system with 4GB of RAM would be set automatically by the operating system, but it’s recommended to have a paging file size at least equal to the amount of installed RAM, if not more, to ensure smooth performance.
