File System Filter Drivers, Extended Validation, Signing via Hardware portal RRS feed

  • Question

  • An earlier blog post "Driver Signing changes in Windows 10" said:

    "Beginning with the release of Windows 10, all new Windows 10 kernel mode drivers must be submitted to and digitally signed by the Windows Hardware Developer Center Dashboard portal.  Windows 10 will not load new kernel mode drivers which are not signed by the portal.

    Additionally, starting 90 days after the release of Windows 10, the portal will only accept driver submissions, including both kernel and user mode driver submissions, that have a valid Extended Validation (“EV”) Code Signing Certificate."

    2 questions:

    1) Does both of these requirements (signing via the portal & needing an EV certificate) apply to File System Filter Drivers, which are kernel mode but don't have any specific associated hardware?

    2) Will a driver signed this way continue to work on Windows XP, Windows Server 2003 & Windows Server 2008?  The blog post does not mention them.

    NB: The portal submission page platforms available to be selected are limited to "Microsoft Windows 10 Client Family x86" and "Microsoft Windows 10 Client Family x64"

    In general, please could Microsoft post more clear documentation regarding the answers to the above?
