I have XP Pro & W7 Enterprise dual booted, with various applications such as VLC player, audacity, spotify, etc installed on my XP, in W7 I go to my XP drive progam files from W7, whatever program I want on W7 now I right click the program .exe file and make a desktop shortcut on W7 desktop ( doesnt have to be on your desktop you can put it anywhere)I am sorry if you all know about this. I just found it for myself. I would not use antivirus in this way.
