I have an issue when executing xp_cmdshell: the returned date format for a DIR command is not the desired one: mm/dd/yy instead of dd/mm/yyyy. I have done some research and it seems to be due to the regional settings of the SQL Server service account. But I am not able to find such account in Windows in order to change its regional settings. How can I change the regional settings of a virtual service account as nt service\mssqlserver?
