Windows 10 Digital Signature

All drivers must be digitally signed by Microsoft before they can be installed and loaded into the Windows kernel in the bit versions of Windows 10. As a result, malware cannot enter the Windows kernel due to this security feature.

The third-party INF does not contain digital signature information and you might see an error message when installing drivers on your computer. Use these steps to fix the issue.

Generally, this error message appears when third-party drivers are installed on a computer. Drivers can be classified into third-party and official in terms of their origin.

The Third Party Inf Does Not Contain Digital Signature Information

As Windows checks for a digital signature, it determines whether a driver has been “signed” or authenticated. That signature gives Windows information about the driver.

This driver differs from the others due to its digital signature, which indicates whether the manufacturer has “signed” it and whether it is genuine. It is important to keep in mind that third-party drivers may also work on your computer, but they are not guaranteed to be stable and may malfunction in a variety of circumstances.

It is necessary for Microsoft to verify any driver that is installed on your computer using Windows Update, original manufacturers’ software, or third-party download software, etc. The electronic security mark authenticates the publisher against the driver and any relevant information about it. It is called “driver signature control” and is used to prevent Windows from running a driver that has not been certified by Microsoft.

It seems my PC won’t boot up because of an error message, “The digital signature for this file cannot be verified.” I’m not an expert in IT, but I’d like to resolve this without spending a fortune on it. Please let me know if this error is fatal or if I can fix it myself? I would greatly appreciate it. Thank you so much.

How to fix the error "Third-party INF does not contain digital signature information"?

While this security feature is important, Microsoft has implemented several backdoors that make it possible for users to install drivers without using digital rules, despite the importance of this feature. We will discuss how to bypass the error message and install the driver without any problems in this article.

There are some third-party drivers that are not trustworthy, and some are even malicious, so you should be aware of that before we get started. Ensure that the driver you are forcing is legitimate and doesn’t pose any risks to your system or computer before installing it. Below you will see how to download the drivers from the manufacturer’s own website.

Note: Make sure that you are logged in as an administrator on your computer and back up your data as a precaution.

Download drivers from the manufacturer’s website

You should definitely check out the manufacturer’s official website to find and download a verified driver before trying other workarounds in which the same driver is forced to be installed. You can follow a general method to install drivers since every player will try to do it differently.

  1. A device label or the device manager will provide you with information about the device that the drivers are being installed from. For more information, click Windows + R and type “devmgmt.msc” in the dialog box that appears.
  2. To install the driver, visit the official website of the manufacturer once you have identified which one you need.
  3. After finding the driver, select your preferred option to download (e.g., from the different versions of Windows). Download the driver in a location that is accessible to you.
  4. The driver can either be installed directly by double-clicking the executable, or by right-clicking on the device in Device Manager and selecting Update Driver.
  5. You can now navigate to the downloaded driver by selecting “Browse My Computer” and entering the location of the driver software.
  6. Check your computer’s performance after installing the driver.

Deactivating driver boost from the command line

It is usually possible to disable roadside checks in two ways. We will use the first method first because it is easier and more efficient than using the autorun options. If you are not already logged in as an administrator on your computer, you may have trouble logging in.

  1. Choose “Run as administrator” from the right-click menu after pressing Windows + S and typing “Command Prompt”.
  2. The following commands need to be run at the command line:
    A few lines of code will enable DDISABLE_INTEGRITY_CHECKS if you use bcdedit /set testsigning on.
  3. Try installing the driver and see if the problem has been resolved. If not, close the prompt and restart your computer.

Disable forced execution via boot parameters

Disabling driver management in Windows startup options may work if the above method does not work. Windows startup options contain several options that allow users to enter a RE state, such as safe mode, etc. You should be logged in as an administrator to be able to access the following options. We will go into the Windows startup settings and try installing the drivers.

  1. Press and hold the Shift key while pressing Restart when you click the Windows icon – Shutdown or Exit.
  2. You will see a blue screen with a number of options on it. Click the troubleshooting button to start Windows in a recovery environment.
  3. Select Advanced Options from the drop-down menu.
  4. You can now customize your startup settings by selecting Startup Settings on the next screen.
  5. You can reboot your computer completely by clicking the Reboot button in the startup settings.
  6. Press the number 7 on the keypad to disable the signature of the driver once your computer has rebooted.
  7. The driver’s digital signature will be disabled when the computer starts up, allowing you to easily reinstall it.

Checking the system files

If you try to install drivers that have been checked by Microsoft and downloaded from the website and the error message remains, it probably means that you have a problem with the Windows files themselves. This scenario can occur if the driver management module is either corrupt or in an error configuration. In this case, we can run a system file check, which scans all your installation files and looks for deviations from the online manifest. If the problem is found, the problem file will be replaced with a new copy.

  1. Right-click the application and choose “Run as administrator” from the dialog box that appears after pressing Win+S, then enter “Command Prompt”.
  2. Make sure you complete the following commands while in the extended command line:
    sfc  /scan now
    Cleaning images, restoring health via DISM
  3. If the system file checks for any problems, this command fixes them. File Checker scans all Windows files according to a predefined manifest. You will be notified if it detects an anomaly and it will download a new copy of the corrupted file from the Internet if it detects one.

Diagnosing a Windows installation

Trying to install a valid driver on your computer but getting an error message when trying to do so suggests that you are having a problem with your Windows installation. If the above methods don’t work, there may be an issue with your Windows installation. The first thing we’ll do is update Windows to the latest version and see if that resolves the issue. If this does not work, we’ll try to restore the system to a previous state. Alternatively, we can install Windows using an ISO image.
