Device Manager is a configuration tool for advanced users who understand configuration parameters and the ramifications of changing them. Checking device properties 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: 1 From the Start screen, type Device Manager. 2 Click or touch Device Manager. The Device Manager screen appears. 3 From the list of device(s), double-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. 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.
