Description of Microsoft System Information (Msinfo32.exe) Tool

This article was previously published under Q184075
Windows 98 includes a tool called Microsoft System Information(Msinfo32.exe). This tool can be used to gather information about yourcomputer, to diagnose issues with your computer, or to access other toolsthat are included with Windows 98. This article describes the MicrosoftSystem Information tool.
Microsoft System Information collects system information, such as devicesthat are installed in your computer or device drivers loaded in yourcomputer, and provides a menu for displaying the associated system topics.You can use Microsoft System Information to diagnose computer issues, forexample, if you are having display issues, you can use Microsoft SystemInformation to determine what display adapter is installed on yourcomputer and view the status of its drivers.

Microsoft System Information also provides access to other tools you canuse for troubleshooting.

Microsoft System Information maintains a history of device drivers thatare installed on your computer. If you are unsure of a computer's recenthistory, use Microsoft System Information to better understand what hashappened in the past. If a device does not work correctly and its historyindicates a recent upgrade to a new driver, replace that driver with theoriginal driver and test to see if the issue is resolved. If you installan update from the Windows Update Web site and it fails to meet yourexpectations, restore the original files by running the Update WizardUninstall from the Tools menu in Microsoft System Information. If yourcomputer worked fine yesterday, but is not working properly today, tryrestoring yesterday's configuration files by running the MS-DOS-basedRegistry Checker program with the /restore parameter.

For more information about how to use the Registry Checker in Windows 98,see the following article in the Microsoft Knowledge Base:

The information displayed in Microsoft System Information is divided intothe following three categories:
  • Hardware Resources
  • Components
  • Software Environment
The following sections describe the categories and sub-categories that aredisplayed in Microsoft System Information, and explain how you can usethis information when you troubleshoot issues with your computer.

System Information

The System Information category provides a general profile of yourcomputer. This information includes:
  • The version of Windows
  • The version of Internet Explorer
  • The type of central processing unit (CPU)
  • The amount of memory and system resources
  • Total and free hard disk space
  • The file system for each partition
Use this information at the beginning of the troubleshooting process todevelop a basic picture of the environment in which the issue occurs.

Hardware Resources

The Hardware Resources category displays hardware-specific settings, suchas assigned or used interrupt requests (IRQs), input/output (I/O)addresses, and memory addresses. The following list is the sub-categoriesincluded in the Hardware Resources category.


Lists the identified resource conflicts between Industry StandardArchitecture (ISA) devices, and identifies resources shared by PeripheralComponent Interconnect (PCI) devices. Use this information to helpidentify hardware conflicts.


Reports the direct memory access (DMA) channels in use, the devices usingthem, and those that are free for use.

Forced Hardware:

Lists hardware devices in which the PnP configuration has been disabledand resource settings have been manually set to user-specified resources. Forced hardware would also apply to devices which do not participate in the PNP process such as legacy ISA devices. This information is useful when you want to troubleshoot Plug and Play resource conflicts.


Lists all I/O port ranges in use and the devices that are using eachrange.


Summarizes IRQ usage, identifies the devices using the IRQs, and listsfree IRQs.


Lists memory address ranges in use by devices.


The Components category displays information about your Windows 98 systemconfiguration. This includes the status of your device drivers, networkcomponents, and multimedia software. There is also a comprehensive driverhistory and a summary of devices that may not be working correctly. Thefollowing list is the sub-categories included in the Components category.

Lists information about your computer's Basic Input/Output System (BIOS),motherboard, and other system devices.

NOTE: You may choose to view Basic Information, Advanced Information, orHistory if the component has a device driver.

Software Environment

The Software Environment category displays the software loaded in yourcomputer's memory.

Drivers - Kernel Drivers:

Lists kernel-mode (ring 0) device drivers that are loaded.

Drivers - MS-DOS Drivers:

Lists real-mode device drivers that are loaded.

Drivers - User-Mode Drivers:

Lists user-mode (ring 3) device drivers that are loaded.

16-bit Modules Loaded:

Lists 16-bit system-level dynamic link libraries (.dll) and programs thatare loaded. This may be useful for debugging software issues, such asapplication fault errors.

32-bit Modules Loaded:

Lists 32-bit system-level DLLs and programs that are loaded. This may beuseful for debugging software issues, such as application fault errors.
