Device driver is a software that is needed for a device to enable it communicate with the Operating system. If a device driver for a particular device fails to install or get corrupted, that device won’t work as it cannot communicate with the operating system.

This means when the operating system is installed, Windows will automatically scan all connected devices, check if it have compatible drivers for these devices in its database and then install the driver.

Once the Windows 10 installation is complete, check device manager to see if all the drivers are installed.

  • If you have unknown device listed, it means Windows don’t have any idea about the device. Windows need you to find the device and install driver for it.
