title: What system-level features new to Windows 10 don't have APIs for programmatic access (yet)?
body: <p>This was pompted by a couple of recent questions where the answer amounted to "there seems to be no API for that" in both cases.</p>
  
  <ul>
  <li><p><a href="https://stackoverflow.com/questions/33641076/retrieving-windows-version-1511">Retrieving Windows version "1511"</a> was about retrieving the "Version 1511" string prominently displayed in the Help / About boxes of system apps from Notepad to MMC since the November update. The only proposed workaround was to read it off an undocumented registry key.</p></li>
  <li><p><a href="https://stackoverflow.com/questions/34210216/how-to-detect-whether-windows-10-features-are-currently-enabled-in-the-console">How to detect whether Windows 10 features are currently enabled in the console</a> was about a console app detecting whether it's running under the "new" console (ForceV2=1) vs. the legacy console. An incomplete and unsatisfactory workaround (that I posted there) was to check whether the console window allows itself to be resized wider.</p></li>
  </ul>
  
  <p>I would expect that there must be more cases of such new features that the published APIs haven't caught up with, yet. Examples welcome, references and known workarounds even better.</p>
