Bug 106 is a problem, but it's really hard for me to communicate with
the bug reporter.
So it may or may not be an invalid report.

Whether /b is used or not, it will exit a script with certain exit code.

In other words, without /b, cmd.exe will terminate with exit code
specified in "exit" command.
With /b, cmd.exe will exit with exit code 0.
When we want to "fetch" the exit code in WPKG Client, /b switch must not
be used.
