I started an installation of a Vista virtual machine but I aborted after it started. I wish to delete the listing of Vista when I first start up Parallels. How do I do that? Thank you.
Right click on the VM you'd like to delete in the Virtual Machines list, select "Delete". Parallels will ask whether you want to delete the VM files as well (that's the virtual hard disk, the control files, etc.) - if you wish to entirely get rid of that VM say "yes". You'll find the files in the trash.
