DebugView 4.9

DebugView is a free Sysinternals (Microsoft) utility for Windows that lets you monitor real-time debug output from applications and device drivers—without attaching a debugger. It captures messages emitted via OutputDebugString from user-mode processes and DbgPrint/KdPrint from kernel-mode components, making it ideal for troubleshooting startup issues, background services, and driver behavior on development and production systems.

Key capabilities:

• Captures both user-mode and kernel-mode debug strings in real time
• Works locally and can capture from remote systems over the network (when configured)
• Provides timestamps and optional process/thread identifiers for each message
• Offers powerful filtering (include/exclude) and search to focus on relevant output
• Logs can be saved or exported for later analysis
• Lightweight, portable, and runs on modern 32- and 64-bit Windows
• Kernel capture requires administrative privileges and the included driver

With its low overhead and immediate visibility into debug traces, DebugView is a go-to tool for developers, support engineers, and IT professionals who need quick insight into what their code or drivers are doing under the hood.

DebugView is developed by Sysinternals. The most popular versions of this product among our users are: 4.2, 4.7, 4.8 and 4.9. The name of the program executable file is Dbgview.exe.
