Next option is very vital. If you choose the desktop class you can use your Oracle database via other software using the localhost and port number 1521. But the enterprise manager   EM Express web interface may not work.

So if you have more than 4GB ram you can choose server class and it is recommended to use full features of Oracle database of any version.

In the account setting, there are 3 account types virtual account existing Windows account create a new account or Windows built-in account.

If you choose virtual account insert database critical security operation you may not be asked any kind of password.  Existing Windows account credential will be used for the security authentication.
