Reinstalling emule doesn't help

I remember that in Windows you can delete some keys from the registry, and re-associate the programs you want to associate, but since it's been a while, I don't remember what those keys are.
I found where the keys are: \Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\

Then you delete 'magnet' and 'torrent' and then try to associate it with the correct program again, and Shareaza will no longer steal the association again.
