You were correct to let Auto Updates run before doing anything else. Windows 7 is driver-complete in the installer and via optional Windows Updates when you enable Automatically deliver drivers via Windows Update (Step 3).

Only if your wireless or ethernet driver is not provided do you need to supply it to get online to do Updates. Only after all Important and Optional Updates are completed should you import any drivers still missing in Device manager, from the Support Downloads webpage for the model PC or device.
