You can. Almost the same way as for unix.
True, you cannot overwrite a running windows program, or a dll that
someone is using. But you can RENAME it. And then put the new version
of the exe/dll. Just as for unix, the new version in not used until
reloaded. Restart exe or restart all exes using a particular dll.
Of course, you need to delete the old renamed file yourself.
And finding all processes using a particular dll may be hard.
So a reboot will fix that for yuo on windows too.
