▷ How to correct “Third-party INF does not contain digital signature information

Users encounter the error message $ 0027 Third-party INF does not contain digital signature information $ 0027 when they try to install third party drivers on their computer. In general, there are two types of controllers present: those of third parties (that are not developed by manufacturers) and the officers (drivers developed by manufacturers).

Third-party INF does not contain digital signature information

The difference between the two conductors is that of a digital signature. A digital signature means if a controller is “signed” by the manufacturer and is authentic. In this case, It should be noted that third-party drivers may also work on the computer, but they do not guarantee stability and may fail in various situations.

Users face this error message when third party drivers are installed on the computer. Although we recommend that you always use the official drivers, it may be necessary to do so. In this article, We will see several ways to avoid this error message and easily fix third-party drivers without interference.

What is an INF file?

An INF file is a type of text file that accompanies a driver and contains instructions for Windows on how to install the driver on your system.. In older versions of Windows (Windows 7 and later), the INF file did not have embedded digital signatures. However, in recent iterations, the function was implemented “apply driver signature”, which ensures that only drivers with valid signatures can be installed. These drivers are usually installed by Microsoft.

Note: before continuing with the solutions, make sure the device you are trying to install drivers from is really legitimate and valid. If the hardware is damaged or cannot be verified, make sure you get to the end of your features and then continue.

How can you force the driver to install by overriding the error message?

Despite the need for this security feature, Microsoft has implemented several back doors that allow users to install drivers on their computer without applying digital drivers.. In this article, we will discuss the ways you can avoid the error message and install the driver with ease.

Warning:

before continuing, It should be duly noted that not all third party drivers are trustworthy and some of them may even be malicious. Before you start to forcibly install drivers, make sure the driver is legitimate and does not pose a risk to your computer or operating system. The best scenario would be to download the drivers from the manufacturer's own site, that we will demonstrate next.

Note: make sure you are logged in as an administrator on your computer and have a backup of your data just in case.

Solution 1: download the drivers from the manufacturer's website

Before trying other solutions where we install the same driver forcibly, it is essential that “try” find and download a verified driver from the manufacturer's official website. Since all readers will try to install different drivers, we have described a generic method that can be followed.

1. The first step is to determine which device is installing the drivers. You can look at the device label or navigate to the device manager (press windows + R, scribe $ 0027 devmgmt.msc $ 0027 in the dialog box and press Enter).

2. After determining the driver you are trying to install, go to the official website of the manufacturer. Downloading drivers from the manufacturer's website

3. Here, after locating the driver, you will have several download options (for example, from different versions of Windows, etc.). Select the one that you think suits your case and download it in an accessible place.

4. Now, you can double click the executable to install the driver directly and, if this doesn't work, you can go back to device manager, right-click on the device and select Update Driver.

5. Now select Browse my computer for driver software and navigate to the downloaded driver.

6. After installing the driver, restart your computer and check if the problem is solved.

Solution 2: disable driver law enforcement by command

Generally, There are two methods through which the driver application can be disabled. One in which we deactivate it using its command line and another in which we deactivate it using the startup options. We will first opt ​​for the first method, as it is easier and more efficient. Make sure you are logged in as an administrator on your computer before continuing.

1. Press Windows + S, scribe “symbol of the system” in the dialog, right-click on the application and select Run as administrator.

2. Once on the command line, run the following command:

bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS & bcdedit /set testsigning on

Disable law enforcement by drivers via command.

1. Now, close command prompt and restart your computer. Now try to install the driver and see if the problem is solved.

Solution 3: disable the app via startup settings

If the above method somehow doesn't work for you, we can go ahead and try to disable the controller app via startup settings. Windows startup settings contain several different options that allow users to enter a RE state., as safe mode, etc. We will access that menu and then we will try to install the drivers. Make sure you are logged in as an administrator.

1. Click on the Windows icon> Shut down or log out> hold down the Shift key and press Restart.

2. This sequence will start Windows into a recovery environment which will be a blue screen with various options. Now click on the Troubleshoot button. Problem solving: Windows RE

3. Now click on the Advanced Options button. Advanced Options – Windows RE

4. On the next screen, select Startup Settings. Startup settings – Windows RE

5. Once in startup settings, click the Restart button to restart your computer completely. Restart your computer

6. After restarting the computer, you will see various startup settings in front of you. Click on the number 7 on your keyboard that corresponds to Disable Driver Signature Enforcement. Disable the driver signature app.

7. After making changes, your computer will start with the controller digital signature application disabled. Now you can easily install the driver that was causing you problems.

Solution 4: run a system file check

If you are trying to install Microsoft verified drivers that are downloaded from the same website and the error message keeps getting, it probably means there are some problems with the Windows files. This scenario can occur when the controller application module is corrupted or has a fault configuration. In this case, we can run a system file check which will scan all installation files and look for any discrepancies in the online manifest. If any problem is found, the problem file will be replaced with a fresh copy.

1. Press Windows + S, scribe “symbol of the system” in the dialog, right-click on the application and select Run as administrator.

2. Once on an elevated command line, run the following commands one by one and make sure they complete:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Running a system file check

1. This last command fixes the problems that the system file checker diagnoses when running the scan. The file checker scans all Windows files against a predefined manifest. If you see any discrepancies, alerts you and tries to replace the faulty file with a fresh copy that you download from the web.

Solution 5: diagnose Windows installation

If all the above methods don't work and, in fact, you are trying to install a valid driver on your computer but cannot do so due to the error message, it probably means there is a problem with the Windows installation. In this case, we will first update Windows to the latest version and see if this fixes a problem. If you don't, we will try to restore from a restore point where the problem did not occur. If even this fails, you can go ahead and install Windows from a new ISO file.

1. Press Windows + S, scribe “to update” in the dialog and open Update Settings.

2. Once in the settings, click Check for updates. Looking for updates – Windows

Windows will now start to check for available valid updates. If you find any, make sure to download and install the updates and also restart your computer properly.

If updating Windows to the latest version doesn't help, we will try to restore the computer. Restore points are set along the way each time a new application is installed or when a new update is installed. In this case, you must guess when your windows worked perfectly. Select that point from the available restore points using the following method.

1. Press Windows + S to launch the start menu search bar. Type »restore» in the dialog box and select the first program that appears in the result.

2. Once in the restore settings, click System Restore at the top of the window under the System Protection tab.

3. Now a wizard will open that will guide you through all the steps to restore your system. Press Next and continue with all other instructions.

Windows restore

1. Now select the restore point from the list of available options. If you have more than one system restore point, will be listed here.

Select restore point

1. Now Windows will confirm your actions one last time before starting the system restore process. Save all your work and backup important files just in case and continue with the process.

You can learn more about the restore system to learn more about what it does and the processes involved.

If even system restore doesn't work properly, you can refer to our article How to clean Windows installation 10. Hopefully, this will solve the problem.
