Here's how to change paging file size in Windows 10/8/7. When Windows runs out of physical installed memory, paging file (virtual memory) may be used.

In Windows operating systems, paging file can be used to back or support the system-committed memory (aka “virtual memory“). Usually, in Windows 10, paging file size is automatically managed by OS itself and you don’t need bother for it.

If your system has a lot of physical memory (RAM) installed, your system will work fine with software which has high memory usage. But if the system is low on physical memory and you’re running software which may require more memory, you might need to change paging file size so that system can utilize virtual memory.

Below mentioned steps will show how to manage or alter paging file size in Windows.
