1. if !strings.Contains(string(out), "command completed successfully") { not work on other language system；maybe if cmd.ProcessState.ExitCode() != 0 {

2. certutil -syncWithWU cost too many time, recommend use certutil -verify directly

@lysShub thanks for your feedback.

I agree we should check exit code regarding point number 1.
For point 2: do you know if verify does grab the lastest certs ?

my test result is, when a required cert missing：
    if exec 'certutil verify xxx.crt' with administrator access, the system will automatically download the missing cert
    otherwise, will verify fail
