I think it's best to let Windows 7 finish the entire installation process before trying to customize your computer. Once the installation is done and you are sure that your computer is working as it should, these tutorials may help:
One other Desktop (tester) and spare Toshba laptop both with SSD's
Running Kaspersky 2016 ISS on all machines config'd identically
Logitec audio stereo systems on each machine (x3)
Canon MG5250MFC
Router/modem TP-Link running WPA2SK
