About this tag
The Sysinternals tag on WindowsForum.com covers Microsoft's free, portable suite of advanced Windows troubleshooting and diagnostic utilities. Discussions highlight how tools like Autoruns, Process Explorer, and Process Monitor reveal hidden startup entries, process details, and file handles that built-in Windows tools like Task Manager do not show. The tag also covers Sysinternals updates, such as the May 7, 2026 release adding packaged app support and process tree improvements, and broader topics like Win32 legacy and Windows on Arm support. Content emphasizes Sysinternals' value for administrators, developers, and power users who need deep system insight without paid utilities.
