Hi Steve,
If you’re developing for Windows 10 or qualified versions of Windows Server, you must use the correct version of the HLK.
Yes, this statement is correct.
For your question:
- You’d better install Windows HLK version 1809 or Windows Virtual HLK (VHLK) version 1809 on Server 2019 and install Windows HLK version 1607 on Server 2016.
- Driver packages that pass Windows Hardware Certification Kit (HCK) testing can be digitally-signed by WHQL.
