# -g (User mode only) Ignores the initial breakpoint in target application. This option will cause the target application to continue running after it is started or WinDbg attaches to it, unless another breakpoint has been set. See Initial Breakpoint for details.
# -G (User mode only) Ignores the final breakpoint at process termination. Typically, the debugging session ends during the image run-down process. This option will cause the debugging session to end immediately when the child terminates. This has the same effect as entering the command sxd epr. For more information, see Controlling Exceptions and Events.
# -Q Suppresses the "Save Workspace?" dialog box. Workspaces are not automatically saved. See Using Workspaces for details.
