Well not really a total mess, but I tried out the windows 8 developer preview in parallels 7 and got my fix from that. I want to completely remove that virtual machine and any files associated with the windows 8 iso. I got my windows 8 dp from the microsoft site and just have the iso saved in my downloads folder. My guess would be delete the virtual machine associated with windows 8 and delete the iso file. Will that clear out everything or will I be leaving behind some files and junk that will just be taking up unnecessary space on my mbp?
