  1. Run the Device Manager console. Again, the easiest way to do this is to open the Run dialog box, type the devmgmt.msc in the text box, then click OK.
  2. Scroll through the list of devices until you find the block labeled Software Components and expand it.
  3. Right-click the Intel Pinning Shell Extensions window and select Uninstall Device from the context menu.
