I'm not good with the entries, but I DO know that you should not be modifying the winapp.ini file. You should only make modifications to the winapp2.ini file. Also, it is always a good idea to post your entries so that an experienced person can tell you if it's good and whether or not you need to make changes before using the entries.
Also, someone ought to REMOVE that RegKey1 line from there, as all it does is cripple Winamp's uninstaller.
It is NO MRU item.

Note, this Winamp entry IS already part of the present winapp2.ini, which is why it's particularly important that someone edit it...
