Windows: After I run the uninstaller, why does the operating system still have reference to Symphony items in the Windows services and in the registry?

The uninstaller uses information from the %EGO_CONFDIR%\kernel\conf\ego.conf file to properly uninstall the product. If the ego.conf file is removed or corrupted, the uninstaller will not have enough information to remove the Symphony Windows services or the items in the registry. You will have to remove these items manually.
