Microsoft’s AU Daemon is associated with Microsoft’s long line up of Office programs. These programs include Word, Powerpoint, Excel, One Note, Outlook, Access, Publisher, and SharePoint. All these programs have the Microsoft AU Daemon installed. It is launched along with the Programs in the background. Basically, Microsoft AU Daemon is a small program that checks for new updates released to the Microsoft Office programs by the company. Its full form is “Microsoft AutoUpdates Daemon“.

If you have a registered account that has a product key, as soon as updates are available it triggers an automatic download and installation process. Updates are downloaded in the background and installed automatically. This tool comes pre-installed with all Office Programs and doesn’t need to be installed separately.

Should You Disable It?

Apparently, there is no huge resource usage by the tool and it has no effect on the usage. It is a great tool that does its job without creating any hassle for the user. Therefore, it is wise that it should be left enabled unless it is causing an issue with the application or high resource usage.
