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.

Only a Windows Administrator can read some Windows log files, such as the Security Event Log. Any system user can view other log files, such as logs that software applications created.

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

How to Read Other Windows Log Files

Many log files that software applications use 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 desired log file and click the Open button

There are also programs that allow the user 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.
