title: Error building sample driver: An SDK corresponding to WDK version '8.1' was not found
body: <p>I used one Windows Driver samples from github (<a href="https://github.com/Microsoft/Windows-driver-samples/tree/master/filesys">Filesys</a>) and tried to build it on Windows 10 with Visual Studio 2015.</p>
  
  <p>I have installed both:</p>
  
  <ul>
  <li>WDK8.1 with its SDK</li>
  <li>WDK10</li>
  </ul>
  
  <p>But when i try to build a project i see this error message:</p>
  
  <pre><code>An SDK corresponding to WDK version '8.1' was not found. Please install the SDK before building.    minispy (Filter\minispy)    C:\Program Files (x86)\Windows Kits\10\build\WindowsDriver.common.targets
  </code></pre>
  
  <p>but SDK of 8.1 is already installed.</p>
  
  <p>Is there any option in Visual studio that i could use to point it to SDK 8.1?</p>
