If all of them quit at the same time, then it should be linked to interruption in power supply. A blown fues or broken connection somewhere.
If they quit invidually, the tachometer could be due to a faulty ignition coil circut for the tachometer or a bad meter cluster.
For the Speedometer, the Vehicle Speed Sensor could be faulty.
For the power window, you need to test for power supply to it.
