title: How to update the built-in Microsoft task library in TFS 2017?
body: <p>What is the process for upgrading the default tasks loaded by Microsoft in an on-premises TFS with no internet connectivity?</p>
  
  <p>According to <a href="https://docs.microsoft.com/en-us/vsts/build-release/tasks/" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/vsts/build-release/tasks/</a> there are several tasks now available and supported in TFS v2015-2018/VSTS that do not appear in my TFS 2017u2 installation (specifically the Download Secure File task).</p>
  
  <p>The default tasks are not shown in the Manage Extension screens and the git repo (<a href="https://github.com/Microsoft/vsts-tasks" rel="nofollow noreferrer">https://github.com/Microsoft/vsts-tasks</a>) does not appear to have any instructions for how to package and install the latest versions in an existing TFS.</p>
