If I want to implement registration in the Security Center using Azure trusted signature on a Windows 7 os, how should I do it?

Question

When I use Azure trusted signature to sign a file with the /integritycheck option, the signature shows as successful. However, on Windows 7, it displays "Windows cannot verify the digital signature for this file," but this issue does not occur on Windows 10.

What should i do?

@kingsofthwdash Thank you for reaching out to us, It sounds like you are experiencing an issue with the digital signature of a file that was signed using Azure trusted signature with the /integritycheck option. The signature shows as successful, but when you try to verify the signature on Windows 7, you receive an error message that says "Windows cannot verify the digital signature for this file."

This issue may be related to the fact that Windows 7 uses a different set of root certificates than Windows 10. If the certificate used to sign the file is not trusted by the root certificate store on Windows 7, then the signature verification will fail.

You can try the following steps:

1. Check the certificate used to sign the file and ensure that it is trusted by the root certificate store on Windows 7. You can do this by checking the certificate chain and verifying that the root certificate is trusted.
2. If the certificate is not trusted, you can try adding it to the root certificate store on Windows 7. You can do this by importing the certificate into the "Trusted Root Certification Authorities" store using the Certificate Manager snap-in.
3. If adding the certificate to the root certificate store does not resolve the issue, you can try disabling driver signature enforcement on Windows 7. This will allow you to install and run unsigned drivers or files. However, this is not recommended as it can compromise the security of your system.

Note: It's worth noting that Windows 7 reached end of support on January 14, 2020, and is no longer receiving security updates. It is recommended to upgrade to a newer version of Windows to ensure that your system is secure and up to date - https://learn.microsoft.com/en-us/lifecycle/products/windows-7.
