This site has the ancient drivers that pre-date the "you're not running a genuine prolific cable" test: https://miklor.com/COM/UV_Drivers.php
I have the 3.2.0.0 drivers working on a Win7 and Win10 box.
Keep in mind that these are old drivers, no updates offered, sometimes windows update might overwrite them when a microsoft update is perhaps being "too helpful".

Very likely a Prolific chipset, which Windows deprecated in 10. Perhaps you can google it with that info. Or get a new USB/serial converter with an FTDI chipset.

It would be helpful if you would give some information on which device you have, chipset, etc.
