Please describe the three types of user accounts offered by Windows 7:  administrator, standard, and guest.

What will be an ideal response?

- An administrator account lets you change any settings, access and change any other users' accounts, install software, connect hardware, and access all the files on a computer.
- A standard user account allows you to access folders and files that you create, use most programs that are installed on the computer, and adjust settings that affect your personal view of the Windows desktop.
- A guest account is designed for situations when you want to allow someone to use your computer without creating a user account.  The guest account can be turned on or off only by an administrator.
