Device Manager provides a way to check and change the 
configuration of a device.

Changing the default settings using Device Manager can cause other 
conflicts that make one or more devices unusable. Device Manager 
is a configuration tool for advanced users who understand 
configuration parameters and the ramifications of changing them.

Device Manager provides a way to view the properties of a device. 
Properties include the name of the manufacturer, the type of device, 
the drivers installed, and the system resources assigned to the 
device. 

To check a device’s properties:

Click Start, Control Panel, System and Maintenance, 
System, and then Device Manager.

To view the device(s) installed, double-click the device type.

To view the properties, double-click the device.

The operating system displays the Device Properties dialog 
box, which provides an array of tabs. They may include:

❖

The General tab, which provides basic information about 
the device.

❖

The Resources tab, which lists resources assigned to the 
monitor, optional external optical drive, optional external 
diskette drive, and other power-using functions. This tab 
does not appear if the device is not using resources.

❖

The Driver tab, which displays the drivers being used by 
the device. This tab also provides options for updating the 
driver or rolling back the driver in case the new version is 
causing a problem.

The tabs that appear in the dialog box vary from one device to 
another.
