Event Viewer is a component of Microsoft's Windows NT operating system that lets administrators and users view the event logs, typically file extensions .evt and .evtx, on a local or remote machine. Applications and operating-system components can use this centralized log service to report events that have taken place, such as a failure to ...
For example, web application authors, wishing to intercept a user's intent to undo the last action, need to "listen" for all the following events: Control+Z on Windows and Linux. Command+Z on Mac OS X. Shake events on some mobile devices. It would be simpler to listen for a single, normalized request to "undo" the previous action.
The event loop almost always operates asynchronously with the message originator. When the event loop forms the central control flow construct of a program, as it often does, it may be termed the main loop or main event loop. This title is appropriate, because such an event loop is at the highest level of control within the program.
Event propagation models, such as bubbling, capturing, and pub/sub, define how events are distributed and handled within a system. Other key aspects include event loops, event queueing and prioritization, event sourcing, and complex event processing patterns. These mechanisms contribute to the flexibility and scalability of event-driven systems.
The Security Log, in Microsoft Windows, is a log that contains records of login/logout activity or other security-related events specified by the system's audit policy. Auditing allows administrators to configure Windows to record operating system activity in the Security Log. The Security Log is one of three logs viewable under Event Viewer.

The message loop is an obligatory section of code in every program that uses a graphical user interface under Microsoft Windows. [1] Windows programs that have a GUI are event-driven. Windows maintains an individual message queue for each thread that has created a window. Usually only the first thread creates windows.
The actual logic is contained in event-handler routines. These routines handle the events to which the main program will respond. For example, a single left-button mouse-click on a command button in a GUI program may trigger a routine that will open another window, save data to a database or exit the application.
