A professional technician is carefully replacing a window handle in a modern residential setting. The technician is dressed in a clean, professional uniform and is using the appropriate tools to remove the old handle and install a new one. The window is modern with clear glass, and the surrounding area is neat, organized, and well-lit, highlighting the quality and precision of the service. The image should convey a sense of expertise, reliability, and attention to detail, making it perfect for promoting window repair and maintenance services in an online store.
