Hi Tonyy-5958,
Welcome to Microsoft Q&A.
SQL Server Native Client combines the SQL OLE DB provider and the SQL ODBC driver into one library that you can use to access data in a SQL Server database. It can be used to create new applications or enhance existing applications that need to take advantage of features introduced in SQL Server, such as multiple active result sets (MARS), user-defined data types (UDT), query notifications, snapshot isolation, and XML data type support. Please refer to this doc for more details.
If you don’t use it, you can uninstall it without any worries.
Best Regards,
Amelia
