How to uninstall Microsoft AutoUpdate?

Issue: Hello. I recently got a pop-up message on my Mac from something called Microsoft AutoUpdate. It claims that it will collect some of the diagnostic data about me. If I do not click “OK,” the prompt returns and it is really annoying to me. What is Microsoft AutoUpdate, and why is it on my computer? I never installed it myself.

Solved Answer

Microsoft AutoUpdate is a legitimate application component designed for Mac operating systems and is used to support and update MS Office and other Windows programs that run on Macs. In some cases, however, users claim that they do not have any type of Windows app installed on their computers and still see prompts from Microsoft AutoUpdate. So, what is going on? Is Microsoft AutoUpdate a virus? Let's try to find it out in this post.

MS Office productivity suite consists of Excel, Word, PowerPoint, Outlook, and other useful programs that are used mainly for work. Fortunately, Mac users can also enjoy this set of apps on Apple products. Note that executable (.exe)[1] files are only usable for Windows systems, so users need to download a particular version for Mac systems.

Just like any other software, Windows apps for Macs need to be updated for better security and features. For that, Microsoft released a specific component that comes pre-installed with MS Office and other applications – Microsoft AutoUpdate. However, multiple users claimed that they never installed MS Office on their Macs, yet the application appeared seemingly out of nowhere – and this is where the term “Microsoft AutoUpdate virus” comes from.

Users are simply unaware that other Microsoft-related applications, such as OneDrive, Visual Studio, would also install Microsoft AutoUpdate component for the smooth updating process of these apps. Note that the video game engine “Unity,” despite being released by Apple, might also be related to the app installed, and users will not find any Microsoft-related apps in the installed app folder.[2]

Thus, forget the “Microsoft AutoUpdate virus” term, as the app is completely legitimate and all the sources that claim it is malware or Trojan[3] are wrong. It is true, however, that most do not know how to eliminate the app, as it sometimes annoys users with the frequent prompts about data collection.

Additionally, just like any update prompt (Flash,[4] for example), users might encounter fake pop-ups on various websites. To avoid downloading fake versions of Microsoft AutoUpdate, make sure it is not coming from Safari, Google Chrome, or another browser – the dialog window should come from the macOS system instead. If you have any doubts about malware, we suggest you scan your machine with or or another reputable anti-malware software.

Nevertheless, if you want to uninstall Microsoft AutoUpdate from your computer, you should follow the provided guide below – we explain each step in detail.

Microsoft AutoUpdate interfaceMicrosoft AutoUpdate interface may not update itself automatically, so if you want to renew it, delete this application and download its latest version

Several people expressed their concern on Microsoft forum[5] why the Microsoft AutoUpdater (the same version) features different user interfaces. For example, version 19 on one Catalina OS displays a renewed AutoUpdater screen, which shows all Microsoft applications that are or have been installed on the machine. At the same time, the other Mac device that runs exactly the same Microsoft AutoUpdater on Catalina does not provide any details except a claim that “Microsoft software is up-to-date.”

I have three computers all running Microsoft AutoUpdater 19 on Catalina.
On my computer I get a totally new screen with list of previously installed Office 365 programs… nicer.
However the other two computers (one identical to mine) gets the old, traditional gray screen that just says “All updated.”
Any idea what is going on?

In this case, you should uninstall Microsoft AutoUpdater as explained above and then download its latest variant from the official Microsoft MAU page.
