After hitting enter or clicking on OK you will get a box that looks like this:

3.) Click Yes to uninstall this or no to keep it. If you select yes the next box will pop up to show you that it is being deleted.

4.) Then you will be given a box saying that you need to reboot your computer. Save all of your work and reboot.

5.) Now there's a few additional things that you will need to delete to have this finalized.
%systemroot%\system32\jview.exe
%systemroot%\system32\wjview.exe
%systemroot%\java
%systemroot%\inf\java.pnf
