Use Microsoft Office Removal Tool to Completely Uninstall Office
Chances are, you probably don’t want to remove Microsoft Office, but sometimes Microsoft Office decides to be a buggy mess and you may need to remove it for diagnostic purposes.
Normally, you’d remove Microsoft Office by simply using the un-installation utility. If removing Microsoft Office this way doesn’t work or you simply want a super clean un-installation, Microsoft also offers a less advertised Office Removal Tool that works much, much better. Here’s how to use it.
Using Microsoft Office Removal Tool
Download the Microsoft Office Removal Tool. The Office Removal Tool should work for any version of Microsoft Office (Office 2007, Office 2013, Office 2016, Office 365) on any modern version of Windows (Windows 7, Windows 8/8.1, Windows 10)
Open the Microsoft Office Removal Tool and follow the instructions as prompted. Once the process is completed, go ahead and restart your system. Microsoft Office should be completely removed.
