I read other user question to you upgrading from XP to windows 7. I did upgrade to windows 7 after using XP many years.
In XP if I wanted to add for example X delete button to windows explorer by right click I could add or remove buttons. Here at windows 7 I don’t see the option and in order to delete I have to work with the mouse.
The three answers you gave to other user you are explaining about the task bar how to customize it.
Please try to point me how to do the customize explorer (not internet explorer).
