how to use putty

Hello Windudes. I have a friend I want to play minecraft with. He said he would host the server. He's great like that. It's also good because my machine is pretty old and only has 32 gigs of ram so it's running really slow now. Anyway he said he didn't want to get hacked by porting the forwards or something so he said I would need to create a tunnel or sometginh. He said I have to open up "cmd" so I did and this window popped with all this text. This is when I said fuck no. I am not a prpgrammer or something. He was being a real asshat saying I just needed to copy paste in this one line or whatever so I ended the skype call right there. Anyway I went to bing.com and typed in the stuff he said "ssh tunnel" to see if a real program existed that could do it for me (i think he was just trying to flex on me with his computer skills trying to make me do all that shit) so there the microsoft ai told me putty invented that tunnel so I went to the first result putty.org that site looks like ass guys I think it's scam so I just went to the next one softonic to download it. I got through the wizard and now I have it installed. I think it's glitchy because now my nvidia card is always really loud but whatevey I just want to play minecraft. can someobe please tell me how to connect to my friends server
