Sorry for the confusion. In your original post you mentioned that you would like to include all local accounts in the report. However, in your example, only the members of the local Administrators group are included. Please clarify which behaviour you would like to implement.
Also, Adaxes will use the Microsoft.PowerShell.LocalAccounts PowerShell module to query local groups and users. Is it guaranteed that this module will be installed on each computer you need to generate the report for, or the module might not be installed on some computers?
Finally, the report can include the local group membership of each local user, but the report columns don't support multi-line or multi-value output. This means that the names of the local groups will have to be listed in a custom column, separated by semicolon or another separator. Please confirm whether this solution meets your needs or not.
