Hello; Allow me to welcome you to the HP forums! Sorry to be the bearer of bad newes, but you should not have downgraded your Win10 laptop to Win7. Laptops especially contain specialized hardware for which, for full functionality, specialized drivers are required -- and these come ONLY from the OEM, in this case, HP. Your PC came preinstalled with Windows 10. If you remove or overwrite the original Win10 on your PC with Win 7, you are going to encounter serious problems as there are no HP Win7 drivers for the new hardware that comes with new machines. MS supplies drivers that provide only basic functionality.

This means that some of the hardware functionality is likely NOT to work if you force a downgrade. That includes functions like the touchpad, WiFi, switchable graphics, USB ports -- to name the functions commonly reported here. That said, someone else might come along and point you to Win7 drivers for other model PCs that that will work with yours -- but if that does not happen, you will then be stuck with a PC with limited functionality as HP is not writing Win7 drivers for their new Win10 PCs.
