After spending a lot of time I tried to remove the Help menu (need to substitute for something else) using different tricks but none worked well. For example:

1. Disabling the help button in the menu bar (didn't work)
2. Commenting last line of "HelpPanel". (Didn't work and the build failed).
3. Commenting in the StandUserUi (same results to 2)

Is it really possible to remove this help menu?
