    How to Manage Virtual Memory Pagefile in Windows 10


    Paging is a memory management scheme by which a PC stores and retrieves data from secondary storage for use in main memory. In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages. Paging is an important part of virtual memory implementations in modern operating systems, using secondary storage to let programs exceed the size of available physical memory.

    For simplicity, main memory is called "RAM" (abbreviated from "random-access memory") and secondary storage is called "disk" (a shorthand for "hard disk drive"), but the concepts do not depend on whether these terms apply literally to a specific computer system.

    Virtual memory is a memory management technique that is implemented using both hardware and software. It maps memory addresses used by a program, called virtual addresses, into physical addresses in computer memory. Main storage as seen by a process or task appears as a contiguous address space or collection of contiguous segments. Windows manages virtual address spaces and the assignment of real memory to virtual memory. Address translation hardware in the CPU, often referred to as a memory management unit or MMU, automatically translates virtual addresses to physical addresses. Software within Windows may extend these capabilities to provide a virtual address space that can exceed the capacity of real memory and thus reference more memory than is physically present in the computer.

    Virtual memory is dynamic. This means that Windows will use more or less virtual memory on the fly as needed by the system. It is recommended that you allow Windows to manage this space unless you have a really good reason to change it (rarely necessary).

    The primary benefits of virtual memory include freeing applications from having to manage a shared memory space, increased security due to memory isolation, and being able to conceptually use more memory than might be physically available, using the technique of paging.

    Basically, a paging file is an area on the hard disk that Windows uses as if it were RAM in addition to the install RAM.

    References:

    By default, Windows automatically manages the pagefile settings for you, but there may be times you may need to manually manage your pagefile. For example:
    • If the C: drive that Windows is installed on is small in size, you may wish to remove the pagefile from that drive, and add a paging file to another drive with more space instead.
    • If you use a lot of memory, then you may wish to add a pagefile to another drive to have available if needed.
    • If you don't use a lot of memory and your pagefile is large in size, you may wish to use a smaller custom size.
    • If you are getting a BSOD PAGE_FAULT_IN_NONPAGED_AREA or KERNEL_DATA_INPAGE_ERROR or Low Memory type error, you may need to use a larger custom size for the pagefile.

    This tutorial will show you how to manage the virtual memory paging file for each drive on your Windows 10 PC.

    You must be signed in as an administrator to be able to make changes to the pagefile.

    8 To Set Size of Paging File on a Specific Drive to be System Managed

    A) Uncheck the Automatically manage paging file size for all drives box. (see screenshot below step 8D)

    B) Select a drive (ex: C: ) you want to have its paging file size system managed. (see screenshot below step 8D)

    9 To Set Size of Paging File on All Drives to be System Managed

    A) Check the Automatically manage paging file size for all drives box, and click/tap on OK. (see screenshot below)

    Manage Virtual Memory Pagefile in Windows 10-system_managed_paging_file_for_all_drives.jpg

    B) Click/tap on OK. (see screenshot below step 4)

    C) Click/tap on OK. (see screenshot below step 3)






    OPTION TWO

    Turn On or Off "Automatically manage paging file size for all drives" in Command Prompt


    Turning on Automatically manage paging file size for all drives will remove any custom size set for paging files on all drives with a paging file, and have the paging file size automatically managed by the system for all drives with a paging file.


    1 Open an elevated command prompt.

    2 Copy and paste the command below you want to use into the elevated command prompt, and press Enter.

    (Turn on (default) "Automatically manage paging file size for all drives")
    wmic computersystem where name=”%computername%” set AutomaticManagedPagefile=True

    OR

    (Turn off "Automatically manage paging file size for all drives")
    wmic computersystem where name=”%computername%” set AutomaticManagedPagefile=False

    3 You can now close the elevated command prompt.






    OPTION THREE

    Change Custom Size of Paging File for Specific Drive in Command Prompt


    1 Open an elevated command prompt.

    2 Copy and paste the command below into the elevated command prompt, and press Enter to turn off "Automatically manage paging file size for all drives".

    wmic computersystem where name=”%computername%” set AutomaticManagedPagefile=False

    3 Copy and paste the command below into the elevated command prompt, and press Enter. This will show you a list of which drives have a paging file, and what their Initial size (min) and Maximum size are currently set to in MB. (see screenshot below)

    wmic pagefileset list /format:list

    If the InitialSize and MaximumSize shows as currently set to 0 MB, then it means it is currently system managed.

    You can change these sizes in the next step for a custom size you want.

    4 Type the command below into the elevated command prompt, and press Enter.

    wmic pagefileset where name=”<drive letter>:\\pagefile.sys” set InitialSize=<custom min size>,MaximumSize=<custom max size>

    Substitute <drive letter> in the command above with the actual drive letter (ex: "C") for the paging file from step 3 you want to set a custom size.

    Substitute <custom min size> in the command above with the custom initial (minimum) size you want in MB (ex: "16") for the paging file on the specified drive (ex: "C").

    Substitute <custom max size> in the command above with the custom maximum size you want in MB (ex: "4985") for the paging file on the specified drive (ex: "C").

    For example: wmic pagefileset where name=”C:\\pagefile.sys” set InitialSize=16,MaximumSize=4985


    5 Close the elevated command prompt.

    6 Restart the computer to apply.


    That's it,
    Shawn

    I'm trying to move my pagefile to another drive, but whenever I reboot I get this message.

    Hello Craig,

    Please go ahead and post a screenshot showing your pagefile settings to see if anything may stand out.

    @Supra,

    As a test, select System managed size and click on OK to see if it may stop trying to create a temp page file on "C" after restarting the computer.

    Nope, that didn't seem to help. However I think it works on my NVMe drive, I'd just prefer it to be on my mechanical "Black" drive. Not sure if that will effect performance badly but I was prepared to experiment.

    Question: If I leave "Automatically manage paging file size for all drives" checked, where will the pagefile be stored? I have 4 drives--C:\, D:\, E:\, and P:\--and I'm assuming that Windows would just put the pagefile on C:\ if this option is checked, correct?

    Hey mate,

    It would depend on what you had set for each drive before checking "Automatically manage paging file size for all drives".

    A pagefile will be stored on each drive you have it turned on for.
