From:

Windows Registry Missing Autostart Attribute after In-place Upgrade of Oracle Database from 11.2.0.3 to 11.2.0.4 (document ID 19 63067.1)

Applies To:Oracle database-enterprise edition-version 11.2.0.1.0 to 11.2.0.4 [Release 11.2]
information in this document applies to any platform.
Symptoms

The database auto start attribute in Windows Registry is removed on upgrade of Oracle database from 11.2.0.3 to 11.2.0.4 (in place upgrade). This prevents Oracle Database to restart on reboot of the system.

Cause

For In-place upgrade you'll need to detach old 11.2.0.3 Oracle_home first, that's where it'll delete Ora_autostart R Egistry entry.

Solution

As detach home operation is deleting registry entry, you'll need to add Ora_autostart registry entry manually after UPG Arde using below command:
