[Windows] Troubleshoot programs that hang – but not crash – with WhatIsHang

[1]We know we can use WinCrashView [2] to analyze crashed programs and BlueScreenView [3] to diagnose Windows’ blue screen of death. How about programs that hang but not crash? Is there a tool to help troubleshoot hung apps? Yes, there is; and it is called WhatIsHang.

WhatIsHang is a tool – by the famous NirSofer – that helps users troubleshoot hung programs by analyzing and displaying relevant information about them. Most of the information displayed about hung programs will only be understood by programmers; so to get your issue solved you may have to export the report to relevant knowledgeable parties. However, other information can be understood by laymen, allowing us normal people the opportunity to solve our issues before running to the geeks.

What exactly does WhatIsHang give us in its reports? The following:

Using WhatIsHang is fairly simple. Run WhatIsHang when a program is hung (program must still be running — WhatIsHang will not work if you close it). Upon launching WhatIsHang will detect any hung programs display them in a list. You must then select the hung program you want to analyze and pressing F9 on your keyboard or go to File -> Get Hang Information. (Alternatively you can do Ctrl + F9 or File -> Get Hang Information – All Threads for an enhanced report.) WhatIsHang will then analyze the program and display relevant information, which you can then export. Exporting reports is done by copying the whole report [F8 or Edit -> Copy Entire Report] or by copying only a part of the report [Ctrl + C or Edit -> Copy Selected Items] and pasting it in an e-mail, message board, text file, etc.

As potentially useful as WhatIsHang is, it does have limitations:
