A dump file can be a useful troubleshooting tool when either the system or application crashes and causes the infamous Blue Screen of Death. However, they also can provide a hacker with potentially sensitive information such as application passwords.

You can disable the dump file by going to the Control Panel, System, Advanced, Startup and Recovery. Once open change the options for Write Debugging Information to None. If you need to troubleshoot unexplained crashes at a later date, you can re-enable this option until the issue is resolved but be sure to disable it again later and delete any stored dump files.
