and i want to show them with different title.

This is the first window that is shown in the taskbar

Answer 1

Just remove the "parent" from your *.cpp file of your other two windows.

Before:

TechRoom::TechRoom(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::TechRoom)

After:

TechRoom::TechRoom(QWidget *parent) :
    QMainWindow(), //Remove here
    ui(new Ui::TechRoom)
