Core admin tasks

Users & groups — create accounts, reset passwords, manage groups (backed by Entra ID).
Licensing — assign the right licences so users get the features they need.
Admin roles — assign least-privilege roles (e.g. Helpdesk Admin) rather than Global Admin for everyone.
Service health & support — monitor service health and manage tickets.

These are the everyday tasks of Help Desk and Desktop Support in a Microsoft environment, complementing Windows Administration.
