How to Read Windows Log Files

Reading Windows log files is an important part of maintaining proper operation and ensuring system security. In addition, log files can be extremely useful in troubleshooting Windows errors.

Some Windows log files, such as the Security Event Log, are only able to be read by a Windows Administrator. Other log files, such as logs created by software applications, can be viewed by any system user.

Each log contains a list of events which have occurred, along with problems, failures and warnings.

How to Read the Windows Application, Security, and Sytem Log Files

The Windows application, security and system log files can be read with a Windows application called "Event Viewer", which is accessed through the Control Panel:

• Click the Start button on the desktop’s Taskbar
• Click the Control Panel menu item
• The Control Panel’s window will open
• In the Control Panel, double-click the Administrative Tools icon
• The Administrative Tools window will open with a list of different icons available

How to Read Other Windows Log Files

Many log files used by software applications are written as plain text file, making it possible to use any freeware text editor, "Notepad" or "WordPad", to read the generated log files. To read .txt files in WordPad:

• Click the Start button on the desktop’s Taskbar
• Click All Programs option
• Click Accessories menu item
• Click WordPad application
• A new WordPad window will open
• Click the File menu
• Click the Open menu item
• Navigate to the log file which you wish to read and click the Open button

There are also programs available which give you the ability to monitor log files as they occur in real-time. Examples of such software include Tail For Win32 and Hoo WinTail. These programs make it easy to read new entries from the bottom (tail) of the log file.
