From what I understand looking HERE starting this summer, WHQL signing is the only way to get a driver to load. The thing I do not grasp, is how do we go about running the WHQL tests without a functioning cert? On April 15th my digicert cross signing cert expires. How would I run a WHQL test with a new driver built April 16th? Typically for either a WHQL or attestation signing I would sign using our cert locally, then run the tests, then submit the package (also signed) and MSFT's portal would add their signature in addition to mine.
Will the WHQL tests be relaxed to run with a non-signed driver? Or do I have to use a test cert? Add if so, will the MSFT portal recognize and strip any test signature that is present? It was fine before, even desirable, to have my company's signature and MSFT's but I don't want a test cert present in a shipping binary even if Windows will ignore it for validation purposes.
