Windows operating systems, as you know, are far from perfect. Therefore, sometimes after the initial installation, in case of unexpected failures or when new equipment is connected, an error message may appear in Device Manager (code 28: Drivers are not installed). Eliminate the problem, it turns out, is very simple.
Unknown Device: Error Code 28 (no drivers installed). The Essence of the Problem
If we consider an error in a general sense, the essence of the problem is that when the device is opened (for example, a webcam when Skype is started), the system does not recognize it due to the lack of a driver necessary for its proper functioning.
The most common causes of an error, when error code 28 is indicated in the description (driver not installed), can include the following factors:
- No driver in the Windows database (for non-standard devices).
- Delete or damage his files.
- The presence of an installed outdated version in the system.
As can be seen from the list, the solution to the problem is limited to reinstalling or updating the device driver. But before correcting the error, for example in Windows 7 (code 28), you need to consider some important points and nuances. It’s these little things that can have a pretty strong impact on the performance of a particular device later on.

How to determine if the device is not drivers (error code 28 in the message)?
Even if the user does not understand which device is mentioned in the error message, or if it is an unknown device, you can view all the problematic components in the standard “Device Manager”. It must be invoked from Control Panel, Computer Management section, or directly from Run Console (Win + R) with the input of the devmgmt.msc command.
All incorrectly functioning parts, devices with missing or damaged drivers are marked with a yellow icon with an exclamation mark. Note: it can be “iron” as well as software components.
Simple troubleshooting method
To correct the situation when a driver error is detected, error code 28 in the accompanying warning, the most logical solution is to reinstall it.
To get started, you can try making an update from the context menu. So you give the system the right to search for the most suitable driver in its own database. If the message that the device has already been installed is the most suitable option, but it still does not work, you should use a special disk (“native” or the same Driver Pack solution). He had to be included in the package with the purchase of computer equipment.
In this case, during the update, please use the installation from the specified source, using the browse button, and choose the correct location (optical media or USB device). If this method doesn’t help and you get another error code 28 (driver not installed), then you can remove it completely from the system first. After this it is necessary to reinstall. It happens that not one but several drivers are integrated in the system. And this causes conflict between them.
Use device information
There is one more effective way to solve the problem. Sometimes it happens that the previous methods don’t work and in the error message the system gives error code 28 Drivers are not installed – she tells you. In this case, you can get out of the situation by entering their search on the manufacturer’s website or on specialized resources
One of them is the DevID site. First, in the “Device Manager” select the problem component and bring up the properties menu, where we go to the details tab. Here in the description below, there are lines of the general form: “PCI \ VEN_number & DEV …”. They contain unique numbers – VEN and DEV (ID), which correspond to a specific type of equipment. Of all lines, the longest describes the device most accurately. It needs to be copied to the clipboard, go to the above source, paste the data into the search field and trigger the search process.
The list of results contains two types of files that can be downloaded a ‘clean’ driver and a smaller self-extracting archive. It is better to choose the first option, taking into account the bitterness of the operating system in which it will be installed. Then, on the download page, click the button with the image of a floppy disk and wait for the download to complete.
Then unzip the archive or place the downloaded driver in a suitable place. And when updating, use the search string on this computer. As before, the scroll button sets the location and activates the installation. If the driver fully and completely matches the device, the yellow icon on the corresponding part of the corresponding part is no longer displayed. This indicates normal operation. In the same site, there are additional utilities that can completely scan the system for absence or presence of faulty drivers online. As a result, you will be prompted to download the missing or problematic components after which they should be integrated into the system as shown above.
Finally, there is another solution to the problem of a error code 28 appearing. No drivers are installed – this is no longer a problem. To avoid problems, you can use an easier way. It is perfect for users who do not want to participate in manual search for some reason.
To do this, install any automatic program such as Driver Booster. It will scan the system and update (or install) the drivers for absolutely all devices on the computer. In addition, the appeal will be focused exclusively on the official resources of the equipment manufacturers. The advantage of such utilities is that many of these devices are constantly running (running in the background), checking what the latest versions of drivers (drivers) look like for each type of device.
