Hello,
Just to confirm -> yes, officially HP as a company does not offer Windows 7 drivers for this computer. Only for Windows 8.
As for your other questions - you can notice above, in my previous post I am providing suggestion to create recovery disc (they contain your Windows 8 HP OEM installation and can restore your computer to factory settings). If you have already installed Windows 7 without any back up before that (e.g. HP Windows 8 restore discs or custom image), and if you do not have any recovery discs, the only way now to get back to your original Win 8 installation is to purchase recovery discs from HP.
Please, contact HP support directly to ask for recovery discs for your computer:

If you already have recovery media (discs or USB), you can proceed directly with recovery.
When you use the recovery discs - you can before that have a look at this article for instructions how to recover:
First choose "Recover your HP desktop computer", then "Recovery from recovery discs"
Do not hesitate to post again if you have any further questions - I would be happy to help !
