SignTool Error: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.
Question:
    When I try to verify I signed my code correctly, SignTool reports the following error:

SignTool Error: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

Answer:
    This is because of the "verify" command you may have run: signtool verify myfile.exe. If you run this command, signtool will use the Windows Driver Verification Policy. In order for your file to "verify" properly you need to include the /pa switch, so that SignTool uses the Default Authentication Verification Policy.

Example:
    signtool verify /pa myfile.exe
