The Third-party INF doesn’t contain Digital Signature Information

The complete error message is as shown below :

Windows encountered a problem installing the driver software for your device
Windows found driver software for your device but encountered an error while attempting to install it.
The third-party INF does not contain digital signature information.
If you know the manufacturer of your device, you can visit its website and check the support section for driver software.

There are two types of drivers.

  1. Official drivers- These are developed by the manufacturers and have a digital signature embedded and are trustworthy and reliable.
  2. Third-party drivers- These are not developed by the manufacturers and do not have a digital signature embedded

An INF file is a text file with the extension “.inf” that contains instructions to install the driver in the system. Until Windows 7, the driver INF files did not have a digital signature embedded. In Windows 8, Microsoft introduced a feature called Driver Signature Enforcement which ensured only the drivers with valid digital signatures are installed. If the user wants to install a third-party driver, an option to disable the Driver Signature Enforcement feature is provided.
