Sysinternals
Sysinternals is a suite of advanced system utilities for Windows, developed by Mark Russinovich and Bryce Cogswell, now owned by Microsoft. It provides tools for troubleshooting, diagnosing, and managing Windows systems, including process monitoring, file and disk utilities, security analysis, and network diagnostics. These tools are widely used by system administrators, IT professionals, and developers to gain deep insights into Windows internals and resolve complex issues.
Developers should learn Sysinternals when working on Windows-based applications or systems to debug performance problems, analyze malware, monitor system behavior, and automate administrative tasks. It is essential for scenarios like investigating high CPU usage with Process Explorer, tracking file access with Process Monitor, or analyzing network connections with TCPView, making it invaluable for Windows development and operations.
