Hi,

Recently, we get the driver signed from hardware dashboard and the certification status is green mark. When we install the signed files on Windows 7 x64 with SP1, the Device Manager shows it cannot verify the digital signature. The OS has installed security update KB3033929 but it still doesn't work.

The files can be recognized as Microsoft Windows Hardware Compatibility with a certified icon.

But the device status of property page is still shown code 52.

The file setupapi.dev.log display the following unsigned driver message.

The security update has installed KB3033929 to support SHA-2 code signing.

Could someone can give me some instructions?

    Our previous driver version got the signature last year (2022-01) is still working and the security update only installed KB3033929. Therefore, in my opinion the new signature is doing some security update that the current OS updates no longer to recognize.

    According to the ESU policy below, the third ESU of Windows 7 is expired on 2023-01. Thus, no security update no working.
