Check the services on which Account it is running ?

It's some time ago I have installed Oracle ... There should have been a step asking for the sys user password. That is required, if you can't use an administrative Windows user to connect.

That is incorrect.  Starting in 12c the Oracle software services run as a Windows user.  I normally choose to create a new user named 'oracle' to make Oracle on Windows similar to Oracle on *NIX.

That user is only to run the database processes.  It has NOTHING to do with the accounts to access the actual database.  By default those a SYS and SYSTEM and as Qlemo suggested:  Earlier in the database setup section, you provided passwords for SYS and SYSTEM.

Those are what you need to connect to the actual database.

it's a security idea which has finally surfaced

before 12, you'd install oracle on windows with the system account
> the system account is admin, by default and can only access the server itself
for example: the system account doesn't have access to network drives

if you want the oracle database to access network resources, you need to run the database with a non-system account
this can be done via services.msc and changing the oracle service to run with an other user
this was a little tricky, as no real checks on necessary priviliges of that user were made.

now oracle has built this "run with a specific user" into the install
this installation type allows you to grant certain priviliges to the user used by the oracle database

the password requests only happen if you install a database
this question in the installer is for all the software running out of this particular home
on linux, installing oracle with a specific user is the default way
this was never the case on windows
