Effective May 1 2019: In order to support Retpoline compiled binaries on Hardware Dev Center and to protect the Windows Driver ecosystem, Microsoft will be treating Retpoline compiled binaries submitted to Hardware Dev Center differently than non-Retpoline compiled binaries.

Hardware Dev Center will be testing every binary that passes through their portal to check to see whether or not it was compiled with the Retpoline flag. If this flag is found, we will mark this submission as “Retpoline = True”.
Hardware Dev Center will inform the submitter that their submission contains Retpoline compiled binaries and that their submission distribution options will be limited.
In practice, this means the following:
