Hello,

Came across latest hardening changes to DCOM CVE-2021-26414. Does this windows update has any impact on this library ?

If you don't want be affected by DCOM and its vulnerability, you really need check this out. It circumvents this kind of hardening issue for classic OPC servers completely and forever.
