Customers are saying

Customers have good things to say about the USB to serial functionality, compatibility with various operating systems and devices, and the ease of use of this adapter cable. Many appreciate its quality and durable construction. However, some customers point out that the cable length is short, and that the lack of included drivers may pose a challenge for some users. Overall, the positive feedback on functionality and ease of use outweighs the concerns about cable length and driver support.

    It didn't come with a disk but windows 8.1 was able to install its own driver. I don't know if that would be the case with an older OS.
