问题 I have found an answer to this question for systems that are attached to an AD domain controller. However, this question is for standalone systems where there is no possibility of attaching to a domain controller. Essentially, air-gapped systems. Short and sweet: Is there a way to list the last time each user changed their Windows password for a non-domain, air-gapped system (either Windows 7 or 10) all at once either as a batch file or PowerShell script? I know that net user {username} |
