One of my common task at work involves me to sign in to multiple Microsoft websites using different Live ID’s (.NET Passport addresses). The problem is that usually I have, like 15-20 Internet Explorer tabs open and sometimes one of these tabs uses one Live ID which I have signed in with, and when I try to open a new site and sign in with another Live ID, the newly opened site uses the already used Live ID, so have to go through every tab and sign-out and then use the other Live ID to sign in, this is a tedious process and a headache at times.
One easy way to solve this is Open a new browsing session. To do this
On the Internet Explorer window, click File => and then click New Session
This will enable you to start a new browsing session in which you will be able to use different Live ID’s.
