HP Already list all the drivers, firmware and software on their suppor page but it is a very long list and you may confuse which to download and install. Here I remake the driver list base on the "what driver you need to install". Other firmware and software is optional and if you need more downloads you can go to hp support page.
Certain drivers already installed along windows 7 installation. You can identify which drivers not yet installed by looking at the device manager for the device marked with yellow. If you didn't know which to install. Just download and install the driver I listed here.
