title: how to run mysql_upgrade on windows
body: <p>I have just upgraded (uninstall, restart, download new installer and installed) MySQL Server for Windows on my 2008 R2 box.</p>
  <p>In the upgrade procedure webpage it says:</p>
  <blockquote>
  <p>To use mysql_upgrade, make sure that the server is running, and then
  invoke it like this:</p>
  <p><code>shell&gt; mysql_upgrade [options]</code></p>
  </blockquote>
  <p>But I can't figure that bit out...
  I'm probably having a mental blank but if I run mysql_upgrade; through the mysql command line client, I get an error 1064: you have an error in your sql syntax etc...</p>
  <p>What am I doing wrong?</p>
