title: How to suppress machine accounts in TFS work items
body: <p>In our TFS implementation, if I create a bug report, in the "assigned to" dropdown, I can see machine accounts (the backup account, and a few others that are mandated by our IT department).</p>
  
  <p>I assume that these accounts appear because they are assigned admin privileges to the local server, and so they are team foundation server admins.  </p>
  
  <p>I would like to know if there is a way to filter out these accounts.  Maybe something similar to the filters that you can apply to Sharepoint as described here: <a href="http://support.microsoft.com/kb/827754" rel="nofollow noreferrer">http://support.microsoft.com/kb/827754</a></p>
