The DevCon utility is a command-line utility that acts as an alternative to Device Manager. Using DevCon, you can enable, disable, restart, update, remove, and query individual devices or groups of devices. DevCon also provides information that is relevant to the driver developer and is not available in Device Manager.
You can use DevCon with Microsoft Windows 2000, Windows XP, and Windows Server 2003. You cannot use DevCon with Windows 95, Windows 98, or Windows Millennium Edition.
