How to use on Windows 10?

Hey sorry this might sound really dumb lol, I've been at this problem for a long time. I am able to run --> telnet mapscii.me --> in cmd and get back "Your terminal is not xterm compatible, please use PuTTY"

Which is very understandable, I then try and use PuTTY and just have no idea what to do. I don't know what server host or IP to connect to and could really use some help. I tried looking for tutorials and couldn't find any and have wasted like an hour learning about PuTTY on youtube please help
