Key notes

  • Microsoft Message Queue (MQSVC) is a technology that allows applications to send messages to other applications or systems.
  • Most people don’t really need this file, especially if you’re an average user, so if you find it lurking in your system and eating up your resources, you can disable it.

The Mqsvc.exe process is a part of the Microsoft Message Queue Server, a service that delivers messages to applications and services.

It is essential for the proper operation of the application, so you should not disable it unless you are sure you don’t need it anymore.

What is the Mqsvc EXE file?

Microsoft message queue is a messaging system that allows programs to communicate with each other over a network. While it is a Windows process, it is not necessarily required by everyone.

Audiences that may benefit from this file include:

  • End users – The message queue allows end users to receive notifications about events in the system. For example, an end user who has requested a service can receive a notification when it is completed.
  • System administrators – System administrators can use message queues to monitor the status of their applications and services or to send messages to end users.
  • Developers – Developers can use message queues to create scalable applications. It’s also useful if they want interoperability between their applications and other platforms, especially in data retrieval.

For a single user who uses their PC for gaming purposes or school work, this is not an essential service and should be disabled, especially if discovered to be causing high CPU usage.

What is the Microsoft message queue used for?

Message queueing is an effective method of communication between processes, applications, and machines. 

They are designed to be a scalable and reliable way of passing messages between applications and services. Other benefits include:

  • Alternative for old messaging platforms –  As opposed to using email, message queues allow you more control over who gets what information to prevent spam or viruses from spreading through your organization’s email servers.
  • Reliability – Message queues provide reliable messaging protocols in event-based software. You’re guaranteed that regardless of network failures or power outages, messages will not be lost.
  • Asynchronous communication – It allows one application to send a message to another application without waiting for a reply from the recipient. The message is stored in a queue until the recipient retrieves and processes it.
