title: "Visual Studio update required" but its up to date
body: <p>I have a fresh install of Visual Studio 2015 community with Windows 10 UWP SDK running in my computer. Recently I tried to open a project that I imported from another computer and when I launch the solution I get the next error message:</p>

  <p>Visual Studio update required 
  One or more projects require a platform SDK (UAP, Version: 10.0.10586.0) that is either not installed or is included as pat of a future update to Visual Studio. </p>
  
  <p>Install the platform SDK to open these projects.</p>
  
  <p>When I click Ok, I see that all my projects in the solution explorer have the text <strong>(update required)</strong> next to them.</p>

  <p>And when I click it, it takes me to the Windows 10 SDK download page to download an SDK that I have already installed over and over again. I have also repaired the solution more than once. And finally I have reinstalled the Visual Studio 2015 again from scratch. </p>
  
  <p>What can I do to make my project work again?</p>
