Active Setup is a mechanism for executing commands once per user early during logon. Active Setup is used by some operating system components like Internet Explorer to set up an initial configuration for new users logging on for the first time. Active Setup is also used in some corporation’s software distribution systems to create an initial customized user environment. To understand why such a mechanism is necessary we need to take a step back.
Active Setup runs before the shell is started, i.e. before the Desktop appears. Commands started by Active Setup run synchronously, blocking the logon while they are executing. Active Setup is executed before any Run or RunOnce registry entries are evaluated because Run(Once) is handled by the shell, Explorer.exe, which is started only after Active Setup is finished.
