How to Uninstall Microsoft Office Completely

Every time the user starts a product from the Microsoft Office suite on a Windows device, it asks to sign in to the Microsoft 365 account to license the Office suite or enter a key. However, this company bought Microsoft Office LTSC. So, they should not sign in to license the product and can use a product key license instead. But it’s not working. In this article, you will learn how to uninstall Microsoft Office from Windows completely.

Introduction

For every Office application that we start on the Windows client, a window appears to license the Office Suite. However, entering the key doesn’t work, and we don’t want to sign in with an account to license it because we don’t have a Microsoft license attached to the user.

The problem is that reinstalling Microsoft Office didn’t help, and it keeps giving this “Sign in to get started” window.

Let’s look at how to completely uninstall Microsoft Office or how to remove all the licenses to prevent issues with licensing when entering the product key.

Office Scrubber tool

The Office Scrubber is an automated script to uninstall, remove, and scrub Microsoft Office (MSI or Click-to-Run) and works for the versions below:

1. All Office

2. Office C2R (365, LTSC, 2024, 2021, 2019, 2016, 2013)

3. Office 2016 (MSI)

4. Office 2013 (MSI)

5. Office 2010 (MSI or C2R)

6. Office 2007

7. Office 2003

8. Office UWP (Office Store Apps on Windows 11/10)

The Office Scrubber tool code is taken from the Microsoft Support and Recovery Assistent (SARA), which no longer works and is now built into the Get Help app.
