what do you mean "it was useless"? Post the query you tried and we can help you correct it

Please find the logic for MSSQL below.
Change it in for MS - Access as per your requirement.
Considering your list as
"Id : UserId : ModifiedDate"

SQL

;with cteRowNumber as (
    select * , row_number() over(partition by Id order by ModifiedDate desc) as RowNum
        from YourTable
)
select *
    from cteRowNumber
    where RowNum = 1
