We're fixing an issue where AutoElevate can't complete an elevation when the UAC prompt opens with a username already filled in, for example because of a Group Policy setting or the application itself. AutoElevate works when the prompt is blank, but a pre-filled username can cause the elevation to fail. The fix changes how AutoElevate answers the UAC prompt so a pre-filled username no longer matters. Vote and follow this post to be notified when it's available.
