In the Windows OS, to grant a user permissions equivalent to root-level permissions (which means full control over the system), the user needs to be given:
* Administrator: The Administrator role provides full control over the system, including the ability to install and uninstall software, change system settings, and access all files and directories.
* Power: The Power User role provides some administrative capabilities but not full control. It is a legacy role with fewer permissions than Administrator.
* Default: This refers to a standard user account with limited permissions.
* Superuser: This term is more commonly associated with Unix/Linux systems and is not a specific role in Windows.
