You can still look up these license keys in the Services & Subscriptions section of your Microsoft Account. The same applies to Office 2016, Office 2019 and Office 2021 licenses that are linked to your Microsoft Account. Note: Microsoft 365 installations don’t require a license key as they activate automatically when you log on to Office with your Microsoft Account. However, for either version there is no need to completely reinstall Office. The proper method to determine or change the Product Key depends on your version of Office or Outlook. While you could simply try one of your Product/License Keys and see if it gets accepted, it’s not a very sophisticated approach. How can I find out which license I've used for which computer and how can I change the key if needed? Microsoft Office should be completely removed.I've got several licenses for Office and Outlook but I'm not sure which one which ones I've used and which ones are free.

Once the process is completed, go ahead and restart your system. You should have an option to select “Microsoft Office products” to remove Microsoft Office using the tool. Open the Microsoft Support and Recovery Assistant and follow the instructions as prompted. The Microsoft Support and Recovery Assistant 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) Using Microsoft Support and Recovery Assistant (Formerly Microsoft Office Removal Tool)ĭownload the Microsoft Support and Recovery Assistant (Formerly Microsoft Office Removal Tool).

If removing Microsoft Office this way doesn’t work or you want a cleaner un-installation, Microsoft also offers a less advertised Office Removal Tool that works much better. Normally, you’d remove Microsoft Office by going through Windows Programs and Features tool and using the Office un-installation utility. 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.
