You did not post the exact model number of the system so I cannot indicate a link to the proper Dell support page. But I would recommend installing the Dell drivers instead of Intel supplied drivers. That is assuming the Wi-Fi card is the OEM factory installed version. Dell commonly modifies hardware such as GPU and Wi-Fi cards for maximum performance so that can create problems using drivers such as those from Intel. And as you know those codes would both show up with drivers that are missing.
try a clean Windows 10 OS install on your parents Optiplex AIO. This will likely automatically fix the driver issue for WiFi BT. Although I am not a fan of Windows 10 downsides, it does have the merit of automatic relevant driver download and installation that works most of the time, thus user friendly (as compared to the older Win 7).
