Perfect completely uninstall Oracle 11g database

Oracle 11g can be uninstalled from the Start menu , and you will need to delete the relevant contents in the registry at the same time.

operating System : WINDOWS10 Professional Edition.

Uninstall steps:

1. Disable Oracle services: Enter Computer Management, in the service, find all services at the beginning of Oracle , right click to select Stop.

2. In the Start menu , locate Universal Installer, run Oracle Universal Installer, and click Uninstall product.

3, in the Product List window, click Expand All, except oradb11g_home1, tick other items, click Delete.

Note that the right image cannot be ticked, otherwise the directly deleted form will not pop up. I wasted 1 hours in this blood lesson.

4. Press the Windows logo key and R key, open the Run window, enter regedit, open the registry , expand HKEY_LOCAL_MACHINE\Software, locate Oracle, delete

5. Expand HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services, and then delete all entries that begin with Oracle.

6. Expand Hkey_local_machine\system\currentcontrolset\services\eventlog\application to remove all entries from Oracle; hkey_classes_ ROOT, delete the entry that begins with Ora.

7. Restart the computer, delete the Oracle directory, delete the Oracle installation directory app, etc. So the uninstallation is complete.
