Change the main menu of a program (C#)

I am looking for someone to change the main menu of a program written in C#. Specifically, I want to change the name of a menu item, reorganize existing items, and update existing items. Additionally, I'm needing help with the coding aspect of these changes. What I don't need is for any new items to be added. If you have experience in making these changes to a C# program, I'd really appreciate your help.
