All my PCs are hand built by me since 1990-s. All Windows installations are from ISO. I haven’t installed a single network or WiFi driver since Windows 7. XP - yes, nothing worked out of the box. But W7 and above the only drivers I install are NVIDIA drivers (it works without them, but the default driver doesn’t have all game optimisations) and printer drivers. Even Bluetooth works out of the box. You don’t even need ADB driver for your Android phone anymore, everything just works out of the box.
I’m also not sure what you’re installing for 1-2 hours, it takes about 10 minutes or so over here. It might be dependent on how fast your storage is though.
