Windows 7, 8, 8.1 Kits Discontinued

Belcarra's USBLAN for Windows 7, Windows 8 and Windows 8.1 digitally signed OEM kits can no longer be made available.  

Historically we cross signed our drivers with a code signing certificate that would authenticate to a Microsoft root certificate using a cross-signed intermediate (i.e. issued to DigiCert and issued by Microsoft).

Regrettably, this is no longer permitted, reference article  

https://learn.microsoft.com/en-us/windows-hardware/drivers/install/deprecation-of-software-publisher-certificates-and-commercial-release-certificates#how-do-production-signing-options-differ-by-windows-version

which basically says:

"Cross-signing is no longer accepted for driver signing. Using cross certificates to sign kernel-mode drivers is a violation of the Microsoft Trusted Root Program (TRP) policy. Certificates in violation of Microsoft TRP policies will be revoked by the CA."

 

“If your driver runs on Windows 7, 8, or 8.1, your driver must be signed through the Windows Hardware Compatibility Program. To get started, see Create a new hardware submission ."
