Description
The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the password. The password for the built-in Administrator account must be changed at least annually or when any member of the administrative team leaves the organization. Organizations that use an automated tool, such Microsoft's Local Administrator Password Solution (LAPS), on domain-joined systems can configure this to occur more frequently. LAPS will change the password every "30" days by default.

(The name of the built-in Administrator account must be changed to something other than "Administrator" per STIG requirements.) If the "PasswordLastSet" date is greater than one year old, this is a finding.
