VBoxSVC.exe and windows host freeze

[ghost]

When I use the tray to start/resume/stop an VM. It will crash the windows ""HOST"" that

a) cannot start the guest VM agin
b) windows HOST cannot shutdown
c) cannot kill the VBoxSVC.exe by any tools (e.g. taskman, taskkill, procexp)
d) If I cannon kill the VBoxSVC, I cannot shutdown windows HOST. As it will wait until the service shutdown.

It is abnormal that it often happen to me, only everything if I have installed VBoxHeadlessTray using it to start/stop/suspend/resume a VM.

I could face no problem, if I use the original GUI to manage the VM.

I am not sure which part goes wrong, the headless itself or this tool.
