How to remove a virutal machine?

[cforput]

I installed VM Ware and put XP on a virtual machine. I can't get my windows key to take and ran out of my 30 days free use. I need to uninstall the virtual machine and reload it in hopes of getting another 30 days to try and get it running. How do i uninstall the current virtual machine I have now?

its just like a real machine. format and install again. Otherwise just delete the disk image and make a new one
