Check Virtual Memory Usage with WMI

Windows Management Instrumentation (WMI) is a simple and fast method to check your system's current and peak virtual memory usage.

These two apps produce the same output information, but have two different types of output - HTML file & TXT file.

HTML output app - WMI - "Recoveros" and Page File Settings (HTML)
Text file output app - WMI - "Recoveros" and Page File Settings (TEXT)

File Output Examples
HTML output version
Text output version

Additional details on the information contained in the output file:

The LEFT column = a portion from the WMI text file output

This is the size of the Page File in MB.
If Virtual Memory settings = "System Managed",
this number should be just over 2x installed physical RAM
(at the time the OS was last installed or the page file was reset)
This system has 2x2 = 4 GB RAM.

Name & location of the Page File
Amount of Virtual Memory currently being used (MB)
Page File description

06-26-2010 - The date the Page File was last allocated
Allocation occurs during OS installation & manual page file reset
For most, this date will be = to the first time you booted your new system or reinstalled the OS
Page File name
Amount of PEAK Virtual Memory used since last boot-up (MB)
Indicates Page File settings = "System Managed"

Problems with WMI?

The WMI Diagnosis Utility

A utility to help system administrators diagnose and repair problems with the WMI service.


WMIDiag.vbs is a VBScript script designed to help you ascertain the current state of the WMI service on a computer. The download package includes the utility itself, a ReadMe file that discusses how the tool works (and how to best use it), and sample spreadsheets that provide information about the default WMI configuration on various versions of the Microsoft Windows operating system.
