Well, you can't because Windows by design removes from RAM code sections
of a program that are not used at the moment, and loads them from the
file.exe again when needed. If the exe file gets changed, the
application would crash.

Windows thus impedes replacing an exe that is running, obviously. It
would be a bad thing in Windows to change the file.

Simply different design, not better nor worse. Different, with different
set of pros and againsts.


Say... but the program could maintain a pointer to the old file and use
it, while the disk lists a new version. Yes... but then instances of the
programs loaded at different instants would behave differently, possibly
causing strange errors. Beside requiring a different filesystem design.

So, no :-)
