Method 3: Using Device Manager for Hardware-Related Software

For software related to hardware, such as printer drivers, Device Manager can be used to remove the driver completely.

Steps to Use Device Manager

1. Open Device Manager:

• Press Windows + X and select Device Manager.

1. Find the Device:
