Microsoft reveals more about DCOM hardening on Windows 11 and 10

We're not sure if you realize this, but Microsoft is in a constant sprint to fix some past bugs and enhance some of the operating systems we use today.

In fact, last month, the tech giant issued a reminder about Distributed Component Object Model (DCOM) hardening.

For those unaware, the Redmond company made these changes for a Windows DCOM Server security feature bypass, a vulnerability tracked under CVE-2021-26414.

Additional DCOM hardening resources have been shared

However, today, Microsoft has released some additional resources on this content and has updated its support page on the matter, which now includes various Available dates for various error events in Windows operating systems.

As you might expect, these changes definitely include Windows Server editions, Windows 10, and Windows 11.
