MSSE and Windows Defender definitions only
Can a command line option be set to only process MSSE and Windows Defender definitions as thought I found a hack by setting some environment variables and using a goto with a duplicate label name batch style hack to do this, it seems official support would be nice. The full download process ought to be run once a month after patch-Tuesday. Yet updating definitions could be run everytime when building something such as MSDART discs which would want the most-recent-to-the-day definitions.
