Managing WMI Setup and Upgrade

WMI is included in Windows 2000, Windows XP, the Windows Server 2003 family, and Windows Millennium Edition. WMI must be installed separately for Windows 95, Windows 98, and Windows NT 4.0. SMS automatically installs WMI on SMS clients if they require it. If you want to install or upgrade WMI, see the Microsoft Web site at

WMI might be upgraded with the upgrade of the operating system or the installation or upgrade of a management application, such as SMS. Verify that the systems using WMI (including SMS) are compatible with the new version prior to upgrading WMI.

If you have modified WMI objects that are defined by WMI, upgrading WMI might overwrite your changes. Therefore, you should avoid changing WMI-provided objects. If you do make such changes, record them so that you can reproduce them after the upgrade.

WMI does not have separate service packs. WMI hotfixes are sometimes included in operating system service packs. WMI hotfixes might be available separately, but hotfixes are only available to fix specific problems that are reported to Microsoft Product Support Services.
