Fixed: Prolific PL2303TA USB to Serial Windows 11 Problem

I have recently updated my machine’s OS from Windows 10 to Windows 11. Everything was working fine. Initially, I have not tested the USB to Serial converter (Prolific PL2303TA USB to Serial Converter). After some days, I was inserting the USB to serial converter into my machine, and it was not working. I have seen the below error (PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER, PLEASE CONTACT YOUR SUPPLIER) when I see the device manager.PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER Problem
