    1. Windows allows you to search online for an updated driver or manually choose a driver that has been downloaded to your PC, just as you can when installing devices normally.
    2. Instead use one of OS/2's drivers to do the job for you.
    3. In some scenarios you may be required to reinstall or update the device driver if you are encoutering any issues with a specific device.
    4. Answer: When a driver is initialised it has the option of installing or not installing, the 1201 error means it is not installing, this could be for anyone of a million
