  • Changes in Driver Installation with Windows 8.1?

    For the last year, we have been installing our configuration only INF driver for a USB device using this:
    rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 MyInf.inf
    The advantage of this over PnPUtil was that it did not show the trust dialog and was suitable for silent install.

    The alternate
    rundll32 setupapi,InstallHinfSection DefaultInstall 132 MyInf.inf
    never worked for us.

    With some recent update of Windows 8.1, this appears to fail. I ended up using PnPUtil, which does work reliably. But I am dealing with the certificate trust dialog.

    Does anybody else have any related experience?
