Executable files that are not MSI or EXE signed by a trusted CA; drivers dated after 2020 (Windows 7 driver development stopped years ago).
If the driver hunt exceeds 90 minutes, switch to a USB capture card + HDMI camcorder (acts as a generic UVC device) or upgrade to Windows 10 LTSC (which supports legacy hardware until 2029). The webcam is a sensor – the driver is the bridge. And for Windows 7, that bridge is slowly collapsing.
