What is Device Manager?
The Device Manager refers to a specific feature or utility of Microsoft Windows. It is actually an extension of the Microsoft Management Console that lists and offers an organized view of the hardware recognized by Windows.
In simple words, it is a device management applet that allows the users to view and manage the hardware devices installed on their computer systems, such as hard drives, keyboards and mice, USB devices, sound cards, and others.

If there is any error in any particular hardware device, the Device Manager will typically indicate it in a specific code for that specific device.
There are typically different error codes used by this Windows utility, each of which has different meanings.
However, it is not a hassle to decipher error codes in Device Manager in Windows because every numerical error code displayed by it is accompanied by a message to explain it in more detail.
Functions of Device Manager
The main function of the Device Manager is to help the users in detecting the hardware devices installed on a PC. It lists all of them and informs about their properties.
In addition to that, the utility also stores the information and settings of the device driver. Apart from that, this specific tool allows the users to:
- Disable and enable most of the installed devices.
- Install or retrieve device drivers.
- Ignore selected devices as and when they fail.
The function of this utility also includes storing other relevant and useful information about the hardware devices, such as:
- The manufacturer
- The type
- The model
The statuses of the devices are also displayed by the Device Manager.
Typically, there are five fundamental statuses shown by this tool. These are:
- Not working properly – It is displayed usually by a black exclamation on a yellow triangle.
- Not recognized – It is usually displayed with a yellow question mark.
- Manually configured (no problem) – This is usually indicated by a blue ‘I’ against a white background.
- Normal (no problem) – This is normally denoted by the common icons of the particular device.
- Disabled devices – Traditionally, it is indicated by a red X, but in the later version it has been replaced with a gray arrow pointing downward over the icon of the device.
Another useful function of the Device Manager is to display those devices that were installed in the PC earlier but are not available at the moment, provided the device was installed successfully earlier.
However, in order to view such devices that were installed earlier but are perhaps hidden now, the users will have to type a specific command in the Command Prompt, which is: set devmgr_show_nonpresent_devices=1.
