If you've ever gotten the dreadful blue screen and have had to reboot the computer, WhoCrashed runs a test of the device drivers that interrupted the normal workings of the operating system. The program asks for confirmation to install a Windows clean-up tool that allows it to detect the anomalies in the computer's performance. This is called the Windows Debugging Package. The scan that WhoCrashed performs indicates the exact driver in the operating system that caused the error, which can help give you an idea when deciding what to do with a certain program: if you should keep it or uninstall it. The file path that generated the error, the error code, the product, and the company that developed the file and brief description are some of the data provided by WhoCrashed.
