Windows 7 allows you to have multiple users sharing the same computer under their own individual accounts. This allows each individual user to have their own location on the computer where they can store their personal documents, pictures, videos, saved games, and other personal data. This also allows the owner of the computer to assign certain accounts the ability to perform administrative tasks like installing software, while limiting other user's abilities.
