Unable to read handle information
The easiest way to generate a dump file is using Task Manager. All you have to do is to find the correct process
and then right click on it and choose the “Create dump file” menu item. When you start working on a dump file sooner
or later you might want to check the handles. In that case you receive the following response :
!handle: extension exception 0x80004002.
