Don’t worry if LAPS is missing from GPO: most likely it’s not being copied to your SYSVOL share and it can be fixed real quick. Obviously, you must have LAPS installed on the machine where you’re trying to create the group policy object on (I installed it on a Domain Controller to keep things simple):

• Copy  C:\Windows\PolicyDefinitions\AdmPwd.admx to \\itdroplets\sysvol\itdroplets.com\Policies\PolicyDefinitions
• Copy C:\Windows\PolicyDefinitions\en-US\AdmPwd.adml to \\itdroplets\sysvol\itdroplets.com\Policies\PolicyDefinitions\en-US
