DEVICE MANAGER

First introduced with the release of Microsoft Windows 95, the Windows device manager is a program that allows a user to view hardware devices and their status. Device manager is available in Microsoft Windows 95, Windows 98, Windows ME, Windows 2000 and Windows XP. 

See my overview section for additional information on how you can get into the device manager.

DEVICE MANAGER ERRORS

Within device manager the user can locate three types of problems: an exclamation mark, a red X, or an Other device.

Exclamation Mark - When a device has a yellow exclamation mark, this is an indication that the device is conflicting with another hardware device.

Red X - Indication that the device has been disabled, removed or that Windows is unable to locate the device.

Other Devices - Windows was unable to locate the drivers for the device and cannot determine the type of device being installed.

Each of the device manager error codes can be found in the below device manager error codes section.

DEVICE MANAGER OVERVIEW

Microsoft Windows 95, 98, and ME users enter the Windows device manager by clicking Start, Settings, Control Panel, System icon, and finally clicking the Device Manager tab.

Microsoft Windows 2000 and XP users enter the Windows device manager by clicking Start, Settings, Control Panel, System icon, Hardware tab, and clicking the Device Manager button.

Users who have a keyboard with a windows key may also quickly get to the system prosperities by pressing the Windows key and the Pause key at the same time.

Also be sure to review my device manager categories section below for a good overview of each of the categories found in the Windows device manager.

Below is a listing of each of the Windows device manager categories and a basic explanation of what you may find in these categories. Knowing what categories are available and what should be contained in these categories can help you easily determine when a hardware device is being detected or not, and have a better understanding of device manager.
