Debug Diagnostics Tool (x86) 1.6

Debug Diagnostics Tool (x86) by Microsoft is a free troubleshooting utility designed to help diagnose and resolve application crashes, hangs, memory leaks, and performance issues in user‑mode processes on Windows. Originally tailored for IIS and COM+ scenarios, it works equally well with any 32‑bit application, making it a go‑to tool for developers, system administrators, and support engineers.

Key capabilities:

• Rule-based monitoring to automatically collect memory dumps on crashes, hangs, high CPU usage, unhandled exceptions, or specific error conditions
• Targeted support for IIS worker processes (w3wp.exe), services, and standalone applications
• Built-in analysis engine that generates detailed HTML reports for crash, hang, and memory leak investigations
• Memory leak tracking with call stacks to help pinpoint leaking code paths
• Flexible dump options (mini, custom, or full) for precise data collection without code changes

The x86 edition is intended for 32‑bit systems and 32‑bit processes. On 64‑bit Windows, it can be installed alongside the x64 version to troubleshoot 32‑bit applications specifically. By combining automated data collection with actionable analysis, Debug Diagnostics Tool (x86) shortens time-to-resolution for complex production issues and streamlines collaboration between operations and development teams.
