WhatIsHang

WhatIsHang is a small-sized and easy-to-use software utility developed to identify all currently active applications which have stopped working but continue to consume system resources. It can compile this information in reports and save it to file.

Portability benefits

As there is no setup pack involved, you can drop the app files in any part of the hard drive and just click the executable to launch WhatIsHang. Otherwise, you can copy it to a USB flash drive to directly run it on any PC with minimum effort.
What's more, unlike most installers, it doesn't modify Windows registry settings or create extra files on the disk without your permission, so no traces are left behind after its removal.

A simple interface shows thorough process info

The GUI is user-friendly, represented by a normal window with a classical structure, where you can ask WhatIsHang to retrieve hang information for crashed programs with one click.
So, you can find out the window title, process name, process and thread ID, along with the path for each app, save selected or all items to file to further analyze it, as well as use a search function when dealing with large amounts of data.
Moreover, you can create an icon for WhatIsHang to integrate into the system tray, make the frame stay on top of other windows, ask the program to start hidden and to automatically fetch the report, as well as run WhatIsHang with administrative rights.

Evaluation and conclusion

The software tool had minimal impact on the overall performance of the computer in our testing, using low CPU and memory. It showed accurate details about programs and quickly generated reports. To sum it up, WhatIsHang can be of great assistance if you want to find terminated processes that are still using system resources.
