A Tip: How to remove Oracle completely from your system

Well, as we all know Oracle products are the ones that cannot be uninstalled so easily. We need to use "Deinstall/UnInstall" option that comes with "Installation" CD. But if by your bad luck or some other conflicts with other installed softwares, you may face some problems while installation only. So now neither the entire software is completely installed nor cannot be uninstalled because of failed installation process. So in such cases, how you can make your computer free of entire[or specific] Oracle products is 

STEP 1: Go to Run -> Enter regedit.exe [It will open Registry Editor for you ]

STEP 2: You will see a Node named as "ORACLE" in it if any of the Oracle Products is installed in your system. As Sub nodes there will be specific products installed in your system.

STEP 3: If you want to delete any specific  Product under "ORACLE" Node, you can delete but beware of the thing ORACLE_HOME is not being shared by it because if you delete any specific product from there, it may not be removed from ORACLE_HOME. And few Oracle Products use existing ORACLE_HOME so if it alreadycontain an entry for that product , you will not be allowed to install again and again until you change the path. So avoid deleting specific products.

Use this tip if and only if you want to remove Oracle completely from your system and normal install/uninstall process fails. *Warning: It is risky process also.*
