My husband & I share a computer,how can I set our hotmail accs so that we can both stay signed in allthe time instead of one having to sign out so the other one can sign in?

My sister came to stay and has now left. She used my windows live to get in her hotmail (I use gmail) but now I cant log her out and me in. I have somehow got all her 1500 odd contacts in my contacts and I dont want them there. If I delete them I guess it would delete them when she wants them too so I just want to log out of hers, but how?

How can I just reverse this , back to my own gmail via windows live and without deleting all her contacts please?

Our hotmail was set up in English, and is now in Chinese characters.  We can read our messages, but not the folders or drop-downs.  Since we can't read Chinese, if there's a language fix, we can't find it.  We can't read the delete, reply, send or any other functions.   This seemed to coincide with a Facebook password change, but we're not sure how one could have completely changed the other.  And I can't find a way to get support to help me directly!  If anyone can help, we'd appreciate it.
How do I delete a hotmail address that was incorrectly typed. I can sign in with the correct address but the wrong one keeps popping up aswell and I would like to delete it ?
