Hi David_Zhu - could you clarify please, if we have Windows client and server machines which are up-to-date with respective Windows Updates as of end of Jan 2023, is it the case that all the DCOM hardening changes are already in place at this time (as long as we have not put the registry keys in place to disable)? 

And that being the case, we can be confident that any application which is working today will remain working after the March Windows Update?

The only change in the March 2023 update is that the ability to disable the DCOM hardening is being removed?

Thank you!
