How to manage Pagefile virtual memory in Windows 10

General information

Paging is a memory management scheme whereby the PC can store and retrieve data from secondary memory for use in main memory.According to this scheme, the operating system will retrieve data from secondary storage in blocks of the same size called pages (pages).Paging is an important part of deploying virtual memory on modern operating systems.These operating systems use secondary memory to allow programs that may have volume beyond the size of available physical memory.

Simply put, the main memory is called random-access memory (RAM), while secondary storage is called disk (short for hard disk drive - hard disk).

Virtual memory is a memory management technique deployed by a combination of both hardware and software.It maps the memory addresses used by a program (called a virtual address) into the real address in the computer memory.The main repository appears as an adjacent address space or a collection of adjacent storage segments.Windows will then manage virtual address space and assign real memory to virtual memory.Hardware devices responsible for translating addresses in the CPU are often referred to as memory management units (MMU).These hardware components will automatically translate virtual addresses to real addresses.Software within Windows can extend these capabilities to provide a virtual address space that can exceed the capacity of real memory.

The main benefits of virtual memory include helping to free applications or managing shared memory capacity and increasing the security of memory separation.

Basically, a paging file (pagefile) is an area on the hard disk that Windows will use as if RAM in case your real RAM is not enough.

By default, Windows automatically manages the pagefile settings for you, but sometimes you may need to manually manage your pagefile manually.For example:

1. When the C: drive, where your Windows is installed, is too small, you may want to move the pagefile away from that drive to another drive with more space.
2. Once you've used a lot of memory, you may want to add a pagefile to another drive to be ready for use when needed.
3. If you don't use much memory while your pagefile is large, you may want to use a smaller custom size.
4. If you encounter BSOD PAGE_FAULT_IN_NONPAGED_AREA or KERNEL_DATA_INPAGE_ERROR or Low Memory errors , you may need to use a larger custom size for the pagefiles.

This article will show you how to manage the pagefile virtual memory for each drive on your Windows 10 computer.

Note: You must log into the system as an administrator to make changes to the pagefile.
