How do I get email addresses out of hotmail drop down A-Z, Please be specific and don’t answer unless you know what you are talking about cause most of the time, I get bogus info

you know, go to type something in TO: window, a drop down appears with all the email addresses it has captured, none of which I want. So I want to delete them all, but windows hotmail did not find it convenient to inform me of how this might be done. I've asked this before, and the answers were all bull, cause none of it worked. I need detailed step by step, accurate information, if you don't mind? If I can't remove will delete account altogether cause sick of the care-less attitude of windows hotmail etc, etc. What else is new? At least I was able to eliminate from gmail. I appreciate aany help, but do need real help, not some bogus bull pulled off ask.com or other sites like that.
