DESCRIPTION
    The Add-LocalGroupMember cmdlet adds users or groups to a local security group. All the rights and permissions 
    that are assigned to a group are assigned to all members of that group.
    
    Members of the Administrators group on a local computer have Full Control permissions on that computer. Limit the 
    number of users in the Administrators group.
    
    If the computer is joined to a domain, you can add user accounts, computer accounts, and group accounts from that 
    domain and from trusted domains to a local group.

NOTES
    
    
        The PrincipalSource property is a property on LocalUser , LocalGroup , and LocalPrincipal * objects that 
        describes the source of the object. The possible sources are as follows:
        
        - Local
        
        - Active Directory
        
        - Azure Active Directory group
        
        - Microsoft Account PrincipalSource is supported only by Windows 10, Windows Server 2016, and later versions 
        of the Windows operating system. For earlier versions, the property is blank.
    
    Example 1: Add members to the Administrators group
    
    PS C:\>Add-LocalGroupMember -Group "Administrators" -Member "Admin02", "MicrosoftAccount\username@Outlook.com", 
    "AzureAD\DavidChew@contoso.com", "CONTOSO\Domain Admins"
    
    This command adds several members to the local Administrators group. The new members include a local user account, 
    a Microsoft account, an Azure Active Directory account, and a domain group. This example uses a placeholder value 
    for the user name of an account at Outlook.com.
