If one dedicates a box to the emulation applications, which is the
recommendation of the vendors, many of the Windows services can be
disabled.  This provides a significant improvement in the reliability
of the underlying OS. Since Windows network connectivity is for
management only, in most cases it should be possible to isolate it
from general network traffic, reducing exposure to the network
security vulnerabilities.

Another option is not to run the emulator under Windows.  vtAlpha's
bare metalapproach, which is a bundled Linux kernel, works well
because the underlying OS is shipped stripped down and tested with the
application; there is no issue with OS upgrades applied on-site
introducing incompatabilities.
