Instead of choosing to reinstall the system, finally completely learned how to unload the Oracle clean, maybe not a big deal of skills, but is a new knowledge of their own, so to write a summary reward yourself, incidentally, my operating system is win10,oracle is 11.

In fact, the main general steps and online sharing of the uninstall of Oracle almost, different is the specific details of the description, if you first uninstall Oracle, please read carefully, the following is my experience sharing.
