What is created for each user the first time the user logs onto windows?

A profile is made the first occasion when that a client sign on to a Windows XP, Windows 2000, or Windows NT® Workstation–based PC. A client profile is a gathering of settings and documents that characterizes the condition that the framework loads when a client sign on. It incorporates all the client arrangement settings, for example, program things, screen hues, organize associations, printer associations, mouse settings, and window size and position. Profiles are not client arrangements and the client has a profile regardless of the possibility that you don't utilize Group Policy.
