Signed INF driver works on the computer where it was signed, not others

Question

My company purchased a Driver Signing Certificate from Go Daddy. I used it to sign a simple INF file that is a driver for some of our USB devices that use Microsoft\'s usbs

Answer 1

Sounds like you need to get your driver certified and signed by Microsoft, which can be achieved by using the Hardware Certification Kit (HCK). But for Windows 10 and up they are using Hardware Lab Kit (HLK). This is how I've signed kernel-mode drivers, which is done after passing the testing and having Microsoft certify and sign the .sys files and .cat files.
