Invoke-Maester -TestId MT.1091Overview
Section titled “Overview”The ‘Registering user is added as local administrator on the device during Microsoft Entra join’ setting determines if the registering user is added to the local administrators group. This setting applies only once during the actual registration of the device as Microsoft Entra join.
Remediation action
Section titled “Remediation action”Within the Entra Portal - Device Settings set ‘Registering user is added as local administrator on the device during Microsoft Entra join’ to None. This one setting is the fix for this test. It applies to devices joined from then on. Devices that were joined earlier keep the users who are already local administrators; to remove them, you can use an Intune account protection policy that manages the built-in Administrators group (see the links below).
