But, hang on. This is performing the same function as inf2cat, right? It certainly can’t apply a Microsoft signature to the CAT file, and without that, it can’t satisfy KMCS. Right?
I do not know the technical details but libwdi/Zadig/libusbK-inf-wizard has been working for quite some time, including Windows XP/Vista/7/8.1/10/11.
There were reports that the method does not work for certain insider version of Windows 10/11. It is also found that the method does not work for Windows 11 on ARM64.
It does have a major pre-requsite that the .sys driver needs to have valid signature.
