If you're having trouble with driver signature enforcement on Windows, it means your system is preventing the installation of drivers that are not digitally signed. This feature is meant to protect your system from potentially harmful software, but it can also block legitimate drivers from being installed or updated. In this guide, you'll learn how to troubleshoot these issues effectively.

What is Windows driver signature enforcement?

Windows driver signature enforcement is a security feature that ensures only drivers signed by a trusted certificate authority can be installed on your system. This helps safeguard your computer from potentially harmful or unstable drivers that could compromise its stability or security. When this enforcement is active, Windows verifies the digital signature of a driver before installation, ensuring the driver is from a verified source and has not been altered.

Common symptoms of driver signature enforcement issues

You may encounter several symptoms when dealing with driver signature enforcement issues:

  • Installation failures of drivers, often with a message indicating that the driver is unsigned.
  • Error messages while trying to update existing drivers, stating that the installation cannot proceed due to signature issues.
  • Devices failing to function correctly or experiencing problems after an attempted installation of an unsigned driver.

These symptoms indicate that driver signature enforcement is blocking your driver installations.

Before you start

Before attempting to resolve driver signature enforcement issues, ensure that:

  • You have administrative privileges on your Windows account.
  • You have a backup of your important files, especially if you're working with potentially unstable drivers.
  • Restart your computer after making changes or before attempting to install drivers.

How to disable driver signature enforcement temporarily

If you need to install an unsigned driver, you can temporarily disable driver signature enforcement by following these steps:

  1. Restart your computer.
  1. As your computer boots, repeatedly press the F8 key until you see the Advanced Boot Options menu.
  1. Use the arrow keys to select 'Disable driver signature enforcement' and press Enter.
  1. After your computer boots into Windows, try installing the unsigned driver again.

How to permanently allow unsigned drivers

If you often need to install unsigned drivers, you may choose to permanently allow them. Here’s how:

  1. Press Windows + R to open the Run dialog.
  1. Type cmd and press Ctrl + Shift + Enter to open Command Prompt as an administrator.

  1. Type the following command and press Enter:

    bcdedit /set testsigning on
  1. Restart your computer.

This command enables test signing mode, allowing the installation of unsigned drivers. However, be aware that this setting may lower your system's security.

Steps to verify if the issue is resolved

After you disable driver signature enforcement or allow unsigned drivers, check if the installation was successful:

  1. Open Device Manager by pressing Windows + X and selecting 'Device Manager'.
  1. Locate the device associated with the driver you tried to install.
  1. Right-click the device and select 'Properties'.
  1. Under the 'Driver' tab, check the driver version and date to confirm it matches the one you installed.
  1. If the driver is listed without errors, the issue is resolved. If you encounter further problems, consider reinstalling the driver or checking for updates on the manufacturer's website.

Conclusion

If you continue to face issues after following these steps, it may be helpful to consult the device manufacturer's support resources for further assistance.
