title: Change language of TFS 2012 after installation
body: <p>I just installed a new Team Foundation Server 2012 in its English version. Is it possible to switch to another language? </p>
  
  <p>I need this for changing the language of the process templates used by the server. Maybe its possible to just update them and leave the server in English?</p>
  
  <p>I'm a little bit afraid of running the upgrade on this machine because I don't know, if upgrade can also mean TFS 2012 EN -> TFS 2012 OTHER.</p>
