maybe an old vulnerable signed driver can be used to load the new version :D. on a more seirous note, i think contact with a person at MS, likely via socials triggering that, might help here. It all depends on the reason for the ban/block/cancel.

if they had a reason other than 'oops mistake' its likely just going to remain in place. (sadly, that is how MS is. if you care for privacy maybe go to BSD)
