Recognize Windows Shutdown

[N. Hamacher]

Hi,

how can i catch / recognize a Windows shutdown - means: a shutdown
signal given by the OS (not by the user)?
I have to save some data before closing the program.
Mybe someone could give me a hint?

Use a shutdownhook:

While that works for command line type applications or demons, it
usually fails for anything with a gui. (The problem is specific to
Windows.) I have an application with a shutdown hook installed, however
if the user logs out the application is terminated before the hook gets
a chance to run.
