EVERYBODY WAN'TS TO USE MY LAPTOP, SIGN IN WITH THERE E-MAIL ADRESS

HOW CAN I DELETE ALL THOSE SIGN IN'S

I'M USING WINDOWS 7

THANK YOU ALL FOR HELP

Why has Hotmail changed again, sign in, can't get to my emails, ALL of them old and new, plus the ones i do see i can't open them to read
or even bloody delete, what is going on and why change, NOT impressed and NOT HAPPY!!

At some point in time I had to sign up for this Passport email, never used it! Have used sympatico address since 1998.  The passport address has to have

shown on my emails at some point in time. Or hotmail users had access to it!  No one seems to have heard of it.  Except now years and years later

someone has sent me an important email to the passport email address.  I have already messed up my sympatico password by trying to change email addresses on my hotmail sign in page.  I have had the email password reset!  Now if someone can direct me as to how to find and get into my Passport Email account!

It appears that many people are losing significant numbers of important emails from active accounts but I have been unable to detect any sign of a helpful response from Microsoft. If anybody found a helpful Microsoft response would you please direct me to it. Note I am not looking for advice on how to recover emails that I have deleted.
When you open windows live mail by cliking on the icon should it open up automatically before you even sign in? If not how do I change this? Using 2011
Sometimes I can´t sign in my messenger error code 81000323 but I have 2 counts and with the other I don´t have any problem
I havent sign in to Hotmail for sometime, and now I need some of my important mails. All of my mail folders are just gone as if they had never been there! How can I get my mails back? Please!
