You can make the decision as to what to touch or leave alone if you read the documentation on the CD that tells you how to install and upgrade the product. That same information can be found at http://technet.oracle.com.

But generally to remove Oracle from a Windows machine.

1. User ORADIM to drop the Windows services: oradim -delete -sid <sid_name>
2. Reboot
3. Drop all directories containing Oracle application and database files including those hidden under C:\Program Files
4. Clean out all Oracle entries in the registry ... carefully avoiding those that refer to Oracle but are not from Oracle such as those related to Microsoft's Oracle ODBC drivers
5. Reboot
