The virtual memory is a hardware element that optimizes the execution of programs and applications efficiently, when you are low in memory Windows prompts you the following message: Your Computer is Low on Memory

When you are low in RAM, the programs and processes work slowly.

To fix this, Windows 10 incorporates virtual memory which serves as a support for physical memory.

Windows 10 connects to the virtual memory defined by default to store some of these memory pages that have less activity in a file called pagefile.sys.

By default, Windows 10 establishes an automatic virtual memory size, but you can edit it in a few steps.

Ideal advice is to verify how much is the maximum RAM capacity supported by your mainboard and make an economic effort to acquire a new memory module that will help optimize the levels of virtual memory.

Method #6: Scan Malware

Some intrusive virus or malware can affect the optimal performance of your memory RAM, leaving you to the error: Your computer is low on memory

To remove Malware on your computer, I recommend you Malwarebytes because it’s also free and works great.

Method #7: Downgrade Windows Version & Architecture

If you are low on RAM and you don’t want to buy more, one thing you can do is downgrade your current Windows version and architecture.
