These are all common questions asked by users on various forums. This post tackles all these questions and more. It will provide everything you need to know about Microsoft Au Daemon and eliminate the need to go searching on Google again. This post is for both Windows and Mac OS users.


What is Microsoft Au Daemon?

I will put your minds at ease right away. No, it is not a threat to your PC, despite the scary-sounding name. Microsoft Au Daemon is an auto-update system of Microsoft that keeps all the office applications up to date.

In fact, Au in the name stands for auto-update, and Daemon refers to a computer program that runs in the background, rather than being under the active control of a user.

What does it do?

Microsoft Au Daemon continuously monitors the Microsoft servers for updates. Whenever there is an update for an application, it automatically starts the download and installation process.

When a user launches Word, PowerPoint, Excel, Access, Outlook, etc., the auto-update system starts running in the background. It ensures that the users have the latest version of those tools.

Is it really necessary?

Yes. There is a reason this software comes preinstalled with every application in the Microsoft Office Suite. Microsoft is constantly releasing new updates and security patches to improve the user experience. Missing some of the security updates can harm the overall safety of your device.

Without Microsoft Au Daemon, the process of manually checking for updates for every application, then downloading and installing them, becomes cumbersome. Unless that is something you like to do, it is nice to have a preinstalled tool do all that heavy lifting.

It doesn’t take up any additional memory, nor does it hamper the performance of your device. If you still have a problem with it and believe it to be bothersome, you have the option of disabling it.
