About Running Windows Services in Oracle Home

Depending on the type of database installation and user account used as the Oracle Home User, Windows services run under low-privileged, non-administrative accounts such as a LocalService, or an authenticated Windows User Account, or as a high-privileged Local System Account (LSA) in Oracle home.
