Can someone explain why this is not just something that Microsoft should patch in windows? i.e how is this not just a windows vulnerability that you can use TrueCrypt to take advantage of? Why are drivers able to escalate privilege at all?
I'd like to see Microsoft allow more drivers to run in user-mode, but this is just the risk you take when installing drivers. Microsoft has been tightening driver signing requirements, so you can at least be sure they're from a known source.
