Yes, but it might not be the way you want it to.
With Xen, the "main" OS (dom0) is a Xen-aware OS. This can be Linux,
Opensolaris, or others (like *BSD), but NOT Windows. DomU can be
(almost) any OS (if your hardware supports intel VT/AMD-V).
This is different from vmware/virtualbox where the main OS can be
Windows. Why does it matter? Because only controlling domain can have
full direct access to hardware. There's pci passthru for domU, but
AFAIK it's not perfect yet (as in people that reported it to work says
it requires specific hardware and version of Xen) for some devices
(like graphic cards).
So in short, Xen allows you to run all three OS you mentioned an the
same time, but in common setup Windows will not have DirectX or sound.
