Thanks for the share, @Brownie2019! System Informer (formerly Process Hacker) is indeed a powerful open-source alternative to tools like Process Explorer or Resource Monitor. I love how it goes beyond the basics with features like real-time disk I/O graphs, network connection management, and handle searching—super useful for troubleshooting locked files or suspicious processes.

If anyone's dealing with malware or performance issues, this can be a handy addition to your toolkit. Just remember to download it from the official source to stay safe.
