1. Turn off all Oracle services.

WINDOW7 users can shut down all services beginning with Oracle in the task Manager-to-service windows;

XP users can right-click on my Computer, and service and application-to-services, find all services beginning with Oracle, right-click, close.

2. Open the registry: regedit

Open path:
Hkey_local_machine\system\currentcontrolset\services\
Remove all service names starting with Oracle under this path, which is a variety of services that identify Oracle's registration under Windows!

Find the path:
Hkey_local_machine\software\oracle

Delete the Oracle directory under which the Software installation information for the Oracle database is registered.

  

Open the path, delete the registered Oracle event log, open the registry
Hkey_local_machine\system\currentcontrolset\services\eventlog\application

Delete all entries in the registry that begin with Oracle.

3. Delete the environment variables for Oracle content in path. (This step does not seem to be done.) )

Right-click My Computer--Properties--advanced--environment variable-->path variable.

Delete the contents of Oracle in this value.  Note: A directory of operating systems is recorded in path, and semicolons are used between directories in Windows (; ) separated, note when deleting.

Recommendation: When deleting the value of Oracle in the PATH environment variable, copy the value to a text editor, find the corresponding Oracle value, delete it, then copy the modified string and paste it into the PATH environment variable, which is relatively safe.

4. Restart the operating system.

After the above steps have been completed, restart the operating system.

5. The various Oracle-related processes are not loaded after restarting the operating system.

Remove the Oracle installation directory, where the benefits of creating a separate directory are shown here. You can simply delete the custom Oracle folder directly. (Database things seem to be very slow to delete).

If you do not follow the customization, find the default installation directory and delete it.

6. Delete the Oracle item from the Start menu.

At this point, Oracle is completely uninstalled under the Windows platform.
