Hello,

Your process for releasing a minifilter driver looks mostly correct. Here are the steps with some additional details:

Obtain an EV Code Signing Certificate: Yes, this is necessary for submitting drivers to Microsoft for attestation signing or HLK certification.

Conduct HLK (Hardware Lab Kit) Testing: This step ensures your driver meets Microsoft's requirements for reliability, security, and performance.

Create a CAB File: Package your driver and test results into a CAB file for submission.

Submit the Test Results and Certificate to Microsoft: Use the Hardware Dev Center to submit your CAB file along with your EV Code Signing Certificate.

Release the Minifilter Driver: Once Microsoft approves your submission, you can release your driver.

Regarding your additional question:

For Windows 10 and Windows Server 2019 or later, it is indeed mandatory to obtain an EV Code Signing Certificate for submitting drivers to Microsoft. This requirement ensures the integrity and authenticity of the driver.
