Windows

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 and delete the key. This contains registry entires for all Oracle products. - If you are running 64-bit Windows, you should also delete the key if it exists. - Delete any references to Oracle services left behind in the following part of the registry ( ). It should be pretty obvious which ones relate to Oracle. - Reboot your machine. - Delete the " " directory, or whatever directory is your ORACLE_BASE. - Delete the " " directory. - If you are running 64-bit Wiindows, you should also delete the " " directory. - Remove any Oracle-related subdirectories from the "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\" directory. - Empty the contents of your " " directory. - Empty your recycle bin. At this point your machine will be as clean of Oracle components as it can be without a complete OS reinstall. Remember, manually editing your registry can be very destructive and force an OS reinstall so only do it as a last resort. If some DLLs can't be deleted, try renaming them, the after a reboot delete them.
