IMHO
The metadata of executable / not executable files depends on the entries
of the file extension in the registry.
This means, if a file has an extension and this extension is known by
the windows registry as executable, it would run it with the program
associated to the file extension.
If there is no extension and / or association of the filetype, the OS
would ask you to select a known filetype and associate it with.
In WinXP SP2 or 2003serverSP1 or better ;-) there is a new form of
controlling what to execute.
It is called "Data Execution Prevention, DEP" :-)
