title: Is it safe to copy over a dll that is used by a running process on Windows XP?
body: <p>This is on Windows XP.</p>
  
  <p>I have a running process (that I'd like to stay running).  If I copy over a dll that it uses (as in, replace it with a newer version), will this cause problems for the running process, or is the code already loaded such that it won't matter?</p>
