Follina vulnerability - reverse the workaround after JUNE 2022 patch?

Question

Hi All

So it appears JUNE 2022 update covers the Follina vulnerability.
However i could not see anywhere about what is recommended with the previous workaround of deleting the registry key.
Once the client is patched with June 2022 update, would the recommendation be to reinstate the deleted registry keys from the workaround?

Thanks,

Hi DavidMoon-1992,

If you have implemented the workaround there will be no need to undo this workaround once the patch is installed.

I hope this answers your question.

Delete the CertificateMappingMethods registry setting only after the June 14, 2022 update has been installed on all intermediate or application servers and all DCs.
