Task Manager is an important Windows application that you can use to display information about the computer s current performance levels as well as manage the programs and processes running on the system. You can open Task Manager by right-clicking an open area of the taskbar and then selecting Task Manager from the context menu or by pressing CTRL+ALT+DEL and then clicking the Task Manager button. The Windows Task Manager dialog box contains five tabs by default: Applications, Processes, Performance, Networking, and Users.

The Applications tab (shown in Figure 12-6) shows the status of the user-level programs currently running on the computer. Services and system applications running in different contexts from the logged-on user are not displayed. For each application listed, the Status column indicates whether the application is running or not responding.

Event Viewer tracks information in different logs. Windows logs include the following:

USE TestDB; GO CREATE PROC Test.spAccountWithdraw @AccountNumber INT ,@AmountToWithdraw DECIMAL(19, 5) AS

Stores program events. Events are classified as error, warning, or information, depending on the severity of the event. An error is a significant problem, such as loss of data. A warning is an event that is not necessarily significant but might indicate a possible future problem. An information event describes the successful operation of a program, driver, or service. The critical error classification is not used in the Application log. Security Stores security-related audit events that can be successful or failed. For example, the Security log records an audit success if a user trying to log on to the computer was successful. Setup Stores setup events. Computers that are configured as domain controllers in an Active Directory directory service domain have log files displayed here.
