What is DCOM configuration?

The distributed component object model (DCOM) is a network version of the component object model (COM) technology that enables cross-network inter-process communication.

DCOM facilitates network object communication by addressing low-level network protocol specifics. This permits the usage of distributed programs, which comprise several processes collaborating to complete a single task.

What happens if I disable DCOM?

Disabling DCOM could lead to several negative outcomes, some of which include:

• Applications might refuse to launch or run properly.
• Your device might become vulnerable to more security attacks.
• Certain Windows features, such as Windows Management Instrumentation (WMI), may be inaccessible.
