Thanks for explaining some more Windows context here.
However, I'm afraid that
load_profile = True
only works with dedicated users, hence needs users with passwords on the Windows PCs.
I'm disappointed that VirtualBox commands apparently require privileges, which normal
Condor jobs do not have......
Or are there other options I could try.....?

By default the user accounts used to run Condor jobs do not have a
registry loaded. If VBox is dependent on something in the user's hive,
then it'll probably fail. I would suggest adding
load_profile = True
into the submit file and see if that works.
