title: Chrome canary headless mode does not work on windows10
body: <p>Google Chrome Canary does not work with headless on Windows.</p>
  
  <p>Chrome headless does not work on windows. 
  The Error happens like following when I tried to execute below code. 
  But it works on non-headless mode.</p>
  
  <p>I know Canary is unstable but I want to using it to learning about web advanced spec.</p>
  
  <p>This error caused by bug in canary?
  Or caused by my code? </p>
  
  <p>code:</p>
  
  <pre><code>from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  op = Options()
  op.binary_location = "C:\\Users\\username\\AppData\\Local\\Google\\Chrome SxS\\Application\\chrome.exe"
  op.add_argument("--headless")
  op.add_argument("--disable-gpu")
  
  driver = webdriver.Chrome("chromedriver.exe", chrome_options=op)
  
  driver.get("http://www.google.com")
  </code></pre>
