 process continue running, you may use the @code{continue} command after
 attaching @value{GDBN} to the process.
 
+On W32 when system detects unhandled exception in a process, it runs default
+exception handler, which starts a debugger, and then proceeds to wait
+indefinitely on an event object. System might ask user to choose a debugger,
+or, if HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug registry key
+is defined, it will run the debugger program with the command specified in
+that key. First "%ld" token in that key will be replaced with the process ID,
+second "%ld" token will be replaced with ID of the event the process is
+waiting upon. Once GDB attaches to the process, it will signal that event,
+allowing execution to continue, and will catch the exception.
