Virtual memory is a crucial concept in computer systems, including those running on the Windows operating system. It plays a vital role in managing the memory resources of a system and allows programs to run efficiently, even when the physical memory (RAM) is limited. In Windows, virtual memory is implemented through the combination of RAM and a file called the page file or swap file. This article aims to explain the concept of virtual memory in the context of Windows and its significance for the readers.

Examples:

1. Configuring Virtual Memory in Windows:

   • Open the Control Panel and navigate to "System and Security" > "System."
   • Click on "Advanced system settings" on the left panel.
   • In the "System Properties" window, go to the "Advanced" tab and click on the "Settings" button under the "Performance" section.
   • In the "Performance Options" window, go to the "Advanced" tab and click on the "Change" button under the "Virtual memory" section.
   • Here, you can configure the virtual memory settings by selecting the desired drive and specifying the initial and maximum size of the paging file.

2. Monitoring Virtual Memory Usage using PowerShell:

   • Open PowerShell with administrative privileges.
   • Use the following command to get the virtual memory usage information:

     Get-WmiObject -Query "SELECT * FROM Win32_ComputerSystem" | Select-Object -ExpandProperty TotalVirtualMemorySize, TotalVisibleMemorySize, FreePhysicalMemory, FreeVirtualMemory
