Ah since someone decided to sticky my post, then I should update it with the fact the Microsoft Virtual PC 2007 is now out of beta and available as a free download:

Also, I see that the DOSBOX 0.7 has recently been released. Although I still use DOSBOX 0.63 for AOD, there is also a DOSBOX 0.65 which works with AOD. However, I think 0.63 does a better job of minimizing and then returning to full screen than later versions.
