Stupid thing to do

I nuked my WinXP install the other night and while installing stuff I installed WinRAR and forgot to have it NOT be the default handler for .rar files. So now when I DC a .rar file WinRAR opens instead of Opus treating the file like a folder. Is there a quick and easy way to fix this?

Thanks.
