The device manager is self-explanatory in terms of its title. In simple terms, this is the platform or interface that allows you to recruit, monitor, control and different drivers. This is a very useful tool, because it can identify a piece of hardware, the driver that it requires and also the potential source for it. That saves you the time of having to trawl the internet for code numbers and potential matches.
However, it must be noted that the latest versions of Windows are typically capable of identifying the vast majority of devices. They will then download the drivers accordingly without even your knowledge. However, the process can fail from time to time. Other people prefer to preserve their memory and resources, so they disable the automatic download. This means that you manually have to seek updates and put them up.
Using the device manager to troubleshoot problems
The first step is to get to the display and then the second is to interpret what the display is saying, before acting on that information. The tool is even more important when you are looking for unknown device managers. The procedures for Windows 8-10 is to right click on the bottom left corner of your screen. Alternatively, you can press the Windows Key + X. Select the device management. If you are using Windows 7 you should press the Windows Key + R. This will bring up a dialogue box in, which you will type the following string: “devmgmt.msc” before pressing enter to start the run process. Others prefer to use the control panel. You can also use the search function which is located on the start screen or start menu.
The next critical step is being able to interpret what you see. There will be some unknown devices and others that are merely malfunctioning. You will find the information you need in the “other devices” section. The ones that have a little yellow exclamation mark over the icon are the ones that have issues and they are the ones that you must address as a matter of urgency. The ones that have a more descriptive name than “unknown” will be generally easier to find because you can quickly Google them up. The important thing is note that you recognize the device or can give it a name, but that it is being “seen” by windows, so that normal functionality can take place.
Identification and other information
Each driver will give you an id, which you can use to search on the internet. In order to get this, you first have to right click on the unknown device and then select the option to view properties. Windows is designed to inform you if you do not have the right drivers. This is what is known as error code 28. Drill down to the details and then the property box. You should then select the hardware ids that are on the presented list. In addition there will be some additional information about the device, which could be useful when you are doing the troubleshooting.
