The Device Manager screen appears. 3 From the list of device(s), click or touch the device type. 4 To view the device(s) installed, double-click or touch 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 device. This tab does not appear if the device is not using resources. ❖ The Driver tab, which displays the drivers being used by the device.

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