Hi @hhwanea,
we had the same issue, CVE-2021-34527 reintroduced - InsightVM - Rapid7 Discuss.
I guess the detection for the registry keys were added to the vulnerability. After we changed the reg keys according to KB5005010: Restricting installation of new printer drivers after applying the July 6, 2021 updates - Microsoft Support, InsightVM showed the vulnerability as remediated.
Kind regards,
Julian
