title: How to change the fork that a repository is linked to
body: <p>I have a repo called at <code>MAIN/repo.git</code> and I've forked it to <code>FORK/repo.git</code>.  I have both of these repos cloned onto my computer for different purposes.  </p>
  
  <p>Using Github for Windows, a bug seems to have switched <code>FORK/repo.git</code> over to <code>MAIN/repo.git</code>, as when I do <code>git remote show origin</code>, the Fetch URL and Push URL are set to the main repo.  How can I switch this back so the corresponding folder on my local machine points to <code>FORK/repo.git</code>, instead of <code>MAIN/repo.git</code>?</p>
