Wondering what virtual memory is and how to fix low virtual memory on Windows 10/8.1/8/7/XP? Read on to get a full knowledge.

What is Virtual Memory?

Virtual memory, also known as swap file, is used to expand your RAM. As we know, a Windows Desktop/Laptop has two types of memory: the HD (or SSD) and RAM. While the HD or SSD is used for long-term storage; RAM is faster than storage and more volatile. Once you shut off the power, everything in RAM disappears.

When the RAM is running out of space for you to run a program or file that you are trying to load, virtual memory comes into play. It uses part of your hard drive to expand your RAM. Well, when you receive the messages of low virtual memory, you can increase the size of your page file.

In Custom size section, the Initial size is the currently allocated paging file size. You can set the Maximum size for the paging file. There is a recommended paging file size for the target drive, which is the value I entered as example. You can set an appropriate size as you like, whereas, keep in mind that Windows restricts paging file size to three times the size of your installed RAM to guarantee system stability.
