title: What is the difference between a WDM driver, a KMDF driver and a UMDF driver?
body: <p>When creating a Windows Driver project in Visual Studio 2012, you have many different options to choose from.</p>
  
  <p>There's a <a href="http://msdn.microsoft.com/en-us/library/windows/hardware/ff554652%28v=vs.85%29.aspx" rel="noreferrer">page on MSDN</a> that helps you with choosing the correct driver model for your device. It however doesn't clearly explain the exact differences between the WDM, KMDF and UMDF driver types, and when to choose which model.</p>
  
  <p>I'm looking for an explanation on the differences between the WDM, KMDF and UMDF driver models, so it's easy for beginning Windows driver developers to choose the correct model.</p>
