Question

On Windows Live Messenger, I signed in to a friends account..?

On Windows Live Messenger, I signed in to a friends account and it said that I was signing in at two locations and asked me which I would like to be signed in on. It had the name of my computer on it.

Will my friend know that I tried to sign into their account, will it show my computer name?

Answers

Your friend would have also seen the "Signed in at two locations" pop-up; and if he/she was payng attention, would know that someone signed in on there account. They may have dismissed it, but chances are, they checked the other location. Your computer name would have shown up yes.

If he/she noticed it was your computer, chances are they will message you.

Your friend can know that someone signed in but he/she wont know who.
