Use Windows Built-in Account or specify a standard Windows User Account (not an Administrator account) to install and configure the Oracle Home. This account is used for running the Windows services for the Oracle Home. Do not log in using this account to perform administrative tasks.
Use Existing Windows User
The account can be a Windows Local User, a Windows Domain User or a Windows Managed Services Account (MSA). You must provide a user name and password for a Windows Local or Domain User. For the MSA account, which is a managed domain account, you only need to provide the user name.
For an Oracle RAC Database or an Oracle Grid Infrastructure installation, you can only use a Windows Domain User Account.
Create New Windows User
Provide the user name and password for the Windows Local User that you want Oracle Universal Installer to create. Confirm the password. The new user that is created is denied interactive logon privileges to the Windows computer. However, a Windows administrator can manage this account like other Windows accounts.
Use Windows Built-in Account
No user name or password is required. Oracle creates Windows Services using Windows Built-in Accounts (LocalSystem or LocalService).
For Database Server installations, Oracle recommends that you use a standard Windows User Account (instead of a Windows Built-in Account) as the Oracle Home User for enhanced security.
Check Microsoft documentation for more information about other Windows accounts.
