That's because when installed they nearly always store a lot of stuff in the registry and maybe even updates to Windows (C++/.NET runtimes, or drivers) as well. On a physical system with two Windows OS you can sometimes fake this by installing into the same common twice, once from each OS, that way both have the correct set of registry entries and OS updates. In this case however that would not be such a good idea: shared folder performance is not good, and anyway it would create too intimate a link IMHO between host and guest (not good for portability or reliability).
sharing applications is definitely the advanced version
personally I share data files & install the applications on each different virtual machine
I have a good base XP sp3 install that I save as an appliance [on a external HDD], which greatly speeds up the initial install process
I use XP to run Itunes & occasionally Netflix, which don't have native linux versions
this requires Guest additions
I'm not sure why OP[original poster] isn't using compatibility mode on windows 7 or does that take more than the base version?
