<p class=MsoPlainText><i><font size=2 color=black face="Courier New"><span
style='font-size:10.0pt;color:black;font-style:italic'>UMDF drivers do not
require Code Integrity Signing since they aren't kernel-mode code. However your
driver package still needs to be signed so that it can't be tampered with &
can be traced back to the author (or you continue to have unsigned driver
popups). And if your package includes any non-Microsoft kernel-mode drivers in
addition to the user-mode driver then the Code Integrity Signing rules apply to
that too.<o:p></o:p></span></font></i></p>
