title: How do I use unsigned driver on windows 7/8/8.1(especially 64 bit)
body: <p>I'd like to automate installing unsigned drivers that need to be tested.
  I hear if I use gui-auto to bypass the driver warning prompts it still refuses to actually use it.</p>
  
  <p>Security isn't an issue. Automation is(f8 option is useless to me, though might be useful to others). We are using Ultimate/Enterprise but others may be using Home editions).</p>
  
  <p>There doesn't seem to be a full answer especially for recent os that I can find(many answers are followed by someone claiming they don't work).</p>
