    I've signed my 64bit KMDF driver and it works as expected. Everything
    verifies that the signing worked, driver installs fine on Vista 64 (fresh
    copy). When the driver installs the user is told that the driver came from
    "CompanyX" and I get the little certificate icon. In other words, all signs
    point to it being signed correctly.

    Once the driver is installed if I go to the device manager and click on
    properties for the device that dialog box says "Digital Signer Company X".
    However, if I click on the "Driver Details" button and select the .sys file
    for my driver that dialog box says "Digital Signer Not digitally signed".
    Why does this 2nd dialog box under driver details seem to think the .sys
    file isn't signed? If I run signtool verify on the .sys file it confirms
    the chain and reports no issues. My driver is not WHQL certified where all
    the other drivers on my machine are and say "Microsoft" in this area.
    What's the deal with the driver details box?

    Thanks in advance,

  2. for my driver that dialog box says "Digital Signer Not digitally signed".

    This means - not WHQL signed.
    Correct, and the particular UI label you mentioned pays attention to WHQL only.

  3. You have to create and sign .cat file.
