However, this user account (Oracle Home User) must be a low-privileged user account that should not be used for database administration. The primary purpose of Oracle Home User is to run Windows services with Windows User Account.
For enhanced security, Oracle recommends choosing the standard Windows User Account as Oracle Home User for Oracle Database installations rather than a Windows built-in account. It can be a Windows built-in account or a Windows User Account. Oracle Home User is the owner of Oracle Services that run from Oracle Home and cannot be changed after installation. Also, beginning in Oracle 12 c, the OraMTS service runs as the Oracle Home user. Beginning in Oracle 12 c, each Oracle Home has its own OraMTS recovery Windows service. OraMTS service will be created for the Oracle Home you installed. You can install OraMTS as part of the Oracle Database Client.
