    How to Increase Paging File Size in Windows 7 OS

    This is a tut made by @Ronin. I am simply posting it with his permission. Its pretty informative and kinda useful if you have an older/low spec machine

    While working with Windows, especially when using Windows XP or above, there might be instances when you have noticed Windows showing a notification saying ‘Low Virtual Memory’. This is because the physical memory, which is the RAM of the computer is full, and even the Paging File (a.k.a. Virtual Memory) that Windows automatically maintains and uses as the virtual RAM is out of space as well.
    This situation usually arise, when working with intense memory-consuming applications or games which requires Gigabytes of system memory or RAM to run.

    The paging file in Windows stores all the most inactive running applications and instances of software, and allows the operating system to perform paging (formerly known as file swapping) between the physical memory and the paging file. When both the physical and virtual memory are overloaded due to heavy applications running in the foreground and background, the system performance remarkably decreases, hence making the end users experience reduced speed.

    Since Windows allows the minimum size of the paging file to be 1.5 times the physical memory (RAM) and can go up to 4 times to maximum, administrators can manually customize the default settings, and modify the paging file size as required. For example, if a computer has 4 GB of RAM installed as its physical memory, the minimum size of the paging file can be 6 GB and can increase up to 16 GB if needed.

    Although Microsoft Windows is configured to automatically manage the paging file size (the virtual memory) according to the consumption, setting the maximum page file size manually might sometimes increase the speed of the computer at the cost of additional consumption of the hard disk space that the increased paging file size would occupy.

    If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file equal to the amount of random access memory (RAM) installed on your computer, and the maximum size equal to three times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes. Here's the steps:
    1. On Desktop, right click on Computer, and then click on Properties.

    2. It will take you to another window. There, in the left pane, click Advanced System Settings. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

    3. A new dialog box will open. There, on the Advanced tab, under 'Performance', click Settings.

    4. Click the Advanced tab, and then, under Virtual memory, click Change.

    5. Clear the first check box for Automatically manage paging file size for all drive.
    6. Select on C:/ drive, since you wanna increase system speed.
    7. Click Custom size, type a new size in Megabytes in the Initial Size (Mb) or Maximum Size (Mb) box, click Set, and then click OK.
    8. Now Restart your OS for changes to take effect.

    Here's a video tutorial on this topic I found on YT:

    pros and cons:
    PROS: The main advantage of paging over memory segmentation is that it allows the physical address space of a process to be noncontiguous. Before paging came into use, systems had to fit whole programs into storage contiguously, which caused various storage and fragmentation problems. Paging is an important part of virtual memory implementation in most contemporary general-purpose OS, allowing them to use secondary storage for data that do not fit into physical random-access memory (RAM).

    CONS: The only little drawback of this trick is disk fragmentation issues. In Windows' default configuration the pagefile is allowed to expand beyond its initial allocation when necessary. If this happens gradually, it can become fragmented. BUT..... Defragmenting your system drives resolves this issues.

    NOTE: Increases in size usually don't require a restart for the changes to take effect, but if you decrease the size, you'll need to restart your computer. It is recommend that you don't disable or delete the paging file directly from system memory. Doing so will show you blue screen of death, if you know what I mean lmao. And, don't use this trick if you're not sure. 0_^
    Have fun!
