How do I delete Outlook and go back to Hotmail?

I hate Outlook. I have 2 hotmail email accounts. It was rather tricky how Outlook suddenly took over my hotmail first hotmail email acct. I was signing in and clicked something and bam, hotmail quickly went away and a few seconds later Outlook took over. I didn't like it but couldn't find a way to change it back to hotmail. So I've been dealing with it for a couple of weeks (and not liking it at all).

Then tonight as I was signing in to my other hotmail acct, wow same thing happened, suddenly without any clear warning Outlook took over my second hotmail acct. I am bloody mad about this. They sent me an email just after they captured my hotmail accts. The email has 4 or 5 things in a list, like getting acquainted with Outlook type stuff. The first items have links associated with them so it is easy to go learn all about Outlook. The last thing on the list says something like "let us know what you think about Outlook, go to "Options" and choose "feedback". It's late and I searched all over for a place to find "Options" and could not find it anywhere. 

 I HATE Outlook. This was SO tricky getting me into this. There was no link option to confirm or any explanation. I was just signing in and click my usual stuff to start checking email and then captured my Outlook. Sorry to be so mad about this or expressing it to you. I just hate computer trickery like this. Something flashed so fast there was no time to read it and no time to understand or decide what to do, it was decided for me. I would greatly appreciate it if anyone could tell me how to change it back to hotmail without closing email accts. If not, I will just close my decade old hotmail accts and go g-mail acct. Thanks in advance for your help.
