Question:
What is a cookie?
Answer:
Think of a cookie as an identification card that's uniquely yours. Its job is to notify the site when you've returned. Cookies should not be confused with viruses. While it is possible to misuse a cookie in cases where there is personal data in it, cookies by themselves are not malicious.
Many Web sites, including Microsoft's, use cookies. Cookies tell us how often you visit pages, which helps us find out what information interests you. In this way, we can give you more of the content you like and less of the content you don't.
