DebugView

DebugView is a lightweight, real-time debugging tool developed by Sysinternals, a company owned by Microsoft. It is designed to monitor and display system-level debugging information, making it particularly useful for troubleshooting issues related to Windows applications, drivers, and system components. The tool captures and logs messages generated by the Windows Debugger (DbgPrint), allowing developers and administrators to observe system activity in real time.

DebugView operates by intercepting debug output that would normally be directed to the kernel debug console or a serial port. Instead, it captures these messages and presents them in a user-friendly interface, enabling users to analyze errors, trace function calls, and monitor system behavior without requiring advanced debugging knowledge. The tool is especially valuable for diagnosing issues in kernel-mode drivers, where traditional user-mode debugging tools may not be sufficient.

The application is simple to use, with a minimalist interface that displays debug messages in chronological order. Users can filter messages by severity level, such as errors, warnings, or informational messages, and save logs for later analysis. DebugView also supports logging to a file, which is useful for capturing extended debugging sessions or for sharing logs with other developers.

DebugView is freely available for download and does not require installation, as it runs as a portable executable. It is frequently used by system administrators, software developers, and IT professionals to diagnose hardware and software issues, particularly those involving low-level system interactions. While it is not a replacement for more advanced debugging tools like WinDbg, DebugView provides a quick and effective way to monitor and troubleshoot system behavior in real time.
