Q: Why are the packages about 6-7MB smaller in comparison with VBox 4.3.14?
A: The X11 drivers as part of the Guest Additions got smaller due to some optimizations in the code. As the same code is compiled for a lot of X11/ versions (and for Linux and Solaris guests), the savings are quite visible (remember, every package includes the Guest Additions .iso).

Q: Will VBox 4.3.16 fix all problems users experienced with the introduction of Windows hardening in VBox 4.3.14?
A: Most likely not all problems but VBox 4.3.16 should work for a lot of more users. If you still have problems with starting VMs on Windows, please provide the VBoxStartup.log file to help us fixing the remaining problems.
