With the new October security update, Microsoft has reported a change in the way Windows checks drivers or drivers, which could lead to an increase in definition errors for Windows 10 users.
And Microsoft provided Error messages Related to the definitions that users may see for all supported versions of Windows 10 and (Windows Server) after installing the October Security Update.
This feature is designed to protect your computer from unknown publishers. Errors occur if Windows cannot verify the publisher of the definitions or if it lacks a signature.
And when installing third-party drivers, you may receive an error saying: Windows cannot verify this definition publisher.
You might also see an error message saying: There was no signature in the subject when trying to view signature properties using Windows Explorer.
According to Microsoft, the error occurs when an unformatted menu file is correctly selected during validation of the driver by Windows, which means the installation process fails.
The software giant says: Windows requires, starting with this version, the validity of (PKCS # 7) encoded (DER) content in the list files, and the list files must be signed according to Section 11.6 of the DER coding description.
The company recommends that users contact their driver or device manufacturer and request an updated driver to correct the problem if Windows 10 is unable to verify the driver.
Microsoft is working to enhance the security of Windows 10 against harmful definitions, but these efforts have focused on safe business personal computers, such as the Surface Pro X.
The October update corrected 87 weaknesses, including a serious flaw in remote code execution in the Windows stack (CVE-2020-16898).
The severity rating is 9.8 out of 10, and this flaw could allow an attacker to gain control of Windows systems by sending malicious Router Advertisement (ICMPv6) packets to an unpatched computer over a network connection.
Microsoft believes that it is possible that exploits will appear for this defect.
