Find out an email adress?

[Varun]

Hi,

if you share the same computer you can get some idea about the webpages he has been visiting and from there may be you can infer if he has another email id or not.

To do this:
Open your web browser (Internet Explorer / Google chrome or whatever you use)
In the browser check for "History" and open it.
In the History you will find name of the websites which have been opened and in some cases it also shows the name of the email inboxes which were opened.

Another way to do this is to download a key logger from the Internet and install it on your computer. Once a key logger is installed it will record each and every key that was pressed on your computer's keyboard. Check the keylogger after he has done working on the computer.

NOTE: Be careful about the keylogger you install from the Internet. They might introduce a virus and can steal information from your machine. I will hold no responsibility for whatever suggestions I have made here.
