I stumbled across this site the other day and it’s incredible - all the official windows ISO’s and full activation scripts. Your options are to use his script to activate extended security updates (ESU) for your current windows, possibly modify your windows 10 to the LTSC or IoT LTSC versions, or fresh install either of those LTSC versions. Plain LTSC is expected to receive security updates until 2027, IoT version will receive security updates until 2032.
