For some hardware starting with the from the mid/late-2013 generation Intel processors ("haswell") and most hardware sold starting in 2014 later, Windows 7 has never really supported the hardware that well, and an increasing number of features are unsupported. I'd recommend at least considering upgrading on machines that age and newer.
