CrashDoctor

Frequent computer users have surely experienced situations when an application crashes for some reason or another. Program crashes may be caused by access to invalid memory locations, very high resource usage and other errors, but the true problem is that this process might result in data loss.

CrashDoctor is a handy tool that focuses on preventing application crashes, giving you time to save important documents and avoid losing information. It acts as a just-in-time debugger for the Windows system, activating itself when a program is unresponsive.

An actual interface is not available, since CrashDoctor automatically launches when a running program is misbehaving. The application detects the process that performed an illegal operation and attaches to the target program, monitoring its execution and displaying the recovery window.

You can easily terminate the faulty process or instruct CrashDoctor to attempt to recover it from the crashing state. Alternatively, the target process can be debugged, instead of trying to recover its crash. In this case, you have to select one of the available debuggers on your system.

You can add new items to the debugger list, as well as modify or delete existing ones. Once the debugging process is initialized, you cannot recover the program from its crashing state anymore.

In addition to this, the application is capable of intercepting if the misbehaving process tries to open and modify a file and immediately creates a backup copy of it, in order to prevent further damage and data loss.

CrashDoctor is not a completely flawless tool and it might not be able to prevent fatal application crashes. In this case, the process is automatically terminated and its exit code is displayed. Although it might not help you on some occasions, CrashDoctor is worth having around.
