It is reasonable to expect that future Hyper-V versions will continue
supporting TimeSync v4 protocol, we, however, only pick it for
VERSION_WIN10. Currently this is not an issue as VERSION_WIN10 is the
maximum protocol version we can negotiate but this may change in future.
Instead of hoping that we won't forget to update it when time comes I
suggest we change the default now.
