Note: this doesn't work with autostarting because that will use
its own, virtual Desktop INF files.

For these to interact properly, VDI mode should share the INF files
with autostart feature (it's pretty annoying that VDI ones are
in source as hex instead of as ASCII).

And autostart should support taking virtual INF file contents
from disk, if they exist, and only otherwise using the builtin
versions.

This assumes the on-disk INF file isn't broken, I'm not sure
how much we can trust that...
