I now have two Windows 7 virtual machines installed - one of which works and one of which now doesn't. I wish to delete the latter and retain the former, but cannot find a way of removing a virtual machine. It will of course, be blindingly obvious to everyone else and, believe me, I have searched for advice, but I am reduced to throwing myself on your tender mercies. How can I remove an unwanted virtual machine from my Mac whilst retaining the second one? I run a 27" quad-core i7 iMac with 1TB HD and 4GB RAM with Parallels Desktop Build 6.0.11822 (Revision 604190; September 14, 2010) running under MacOSX.6.4 Build 10F569. My Windows 7 version is 64 bit Professional. Thanks in advance.
