Hello, This is my first time on here and first time working with oracle database. So my problem is that after i installed 18c XE and check the service on my computer there is no OracleServiceORCL. So its like i lost connection to the server completely, i used to have 11c and i manually uninstalled it for the 18 which i followed online and end up deleting the server in service on my computer. How do i get that back so i do not have this error.

Thank you for any replay
