In my test case ( I also added a shutdown hook but this app is
spawned as a child process from signals.exe with the CREATE_PROCESS_GROUP
flag enabled. This causes the Win32 kernel to call SetConsoleCtrlHandler on
behalf of the CreateProcess call and disable the CTRL-C handler (See the
MSDN entry for CreateProcess). Therefore child apps can only be killed  by
sending a CTRL-BREAK event. The effect on this is that the VM does not call
the shutdown hooks (And you have to call java with the -Xrs parameter
otherwise you will see just a thread dump of your child process)....

So I see your problem. We are currently not using any Shutdown hooks in our
Java services, but I suspect that we might be in the future and then we will
run into the same troubles you are facing today...

So I'm definitely interested in a solution of your problem as well....
