WD clean up

I have had a registered copy of WD for quite a few years and what I want to do is clean up my hard drives of two different locations and go back to only having it on my C drive. In other words, I have WD installed on my C and G drive and I want to remove WD from both drives and reinstall on my C drive only. How can I do this when I no longer have my registration key.

Thanks
John
