IMenuManager menuManager = getWindowConfigurer().getActionBarConfigurer().getMenuManager();
IContributionItem[] items = menuManager.getItems();
if (items.length != 0) {
for (int i = 0; i < items.length; i++) {
if (items[i].getId().equals("org.eclipse.search.menu")) {
menuManager.remove(items[i]);// delete search and menu
continue;
}
if (items[i].getId().equals("help")) {
MenuManager helpmenuManager = (MenuManager) items[i];
IContributionItem[] helpitems = helpmenuManager.getItems();
for (int j = 0; j < helpitems.length; j++) {
if (helpitems[j].getId().equals("group.assist")
|| helpitems[j].getId().equals(
"org.eclipse.ui.actions.showKeyAssistHandler")) {
// delete Key Assist menu
helpmenuManager.remove(helpitems[j]);
}
}

}
menuManager.updateAll(true);
