title: WACK check in build
body: <p>I have UWP application that I'm working on and also setting up CI for it.
  I want to include Windows App Certification Kit (WACK) as a build step to verify all the  builds application against MS rules.</p>
  
  <p>CI is build on the top of Visual Studio Online.
  There is an custom Build Agent with the latest software installed attached to my VSO build configuration.
  The problem is that WACK requires admin privileges to run, however VSO requires that user that runs BuildAgent should not have admin privileges.</p>
  
  <p>Is there any way to increase privileges of the user during build run?
  Is there any workaround to run WACK without admin privileges? 
  Even if some of the WACK tests are disabled it still make sense to integrate WACK check into CI.</p>
  
  <p>Appreciate any help.</p>
