You need to remove c:\program files\oracle as well as a bunch of registry stuff as well. There's a metalink doc on it if you want to get real clean, but getting the obvious registry stuff usually works ok.

HKLM\software\oracle
HKLM\system\CurrentControlSet\services\Oracle*

You'll need a reboot to clear the deleted services. Use oradim to recreate any services needed for existing databases (also see the migration stuff...).
