How to manually remove Oracle 10g instance from Windows 2003

Hi experts,

I need to remove a Oracle 10g database instance from Windows 2003. The steps that I've looked up appear to simple. Can you give me the instuctions in a step by step manner? This is a dev/play db so I really can't mess it up.

Thanks,

step1: remove the DB using DBCA
step2: remove oracle Home using Oracle universal installer

In the past I've had many problems uninstalling all Oracle products from Windows systems. Here's my last resort method:

Uninstall all Oracle components using the Oracle Universal Installer (OUI).
Run regedit.exe and delete the HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE key. This contains registry entires for all Oracle products.
Delete any references to Oracle services left behind in the following part of the registry (HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*). It should be pretty obvious which ones relate to Oracle.
Reboot your machine.
Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
Delete the "C:\Program Files\Oracle" directory.
Empty the contents of your "C:\temp" directory.
Empty your recycle bin.

If you want to remove 10G database instance only then as suggested by others by using DBCA.

If you wish to completely uninstall Oracle from the machine, you can refer http://docs.oracle.com/cd/B19306_01/install.102/b14316/deinstall.htm
