This has always been the same afaik. I think it is an inconsistency in
how Windows checks the signature.

I believe it is enough if the catalog file is signed. If my memory
serves me correctly the sys file could be signed at some point in the
history of Windows.

If you can test 64-bit Windows 10 with Secure boot enabled which is not
an upgrade from Windows 7/8 that would be optimal. I've been told that
combo is the most picky about signatures.
