Step 1: Click File at the top of the ribbon.

Step 2: Click Account in the sidebar at the bottom left. For some Office products, this menu item is called Office Account. If Account is not displayed, you can alternatively select Help. Step 3: On the right under Product Information the name of the Office version used is displayed.

Under “Account” you can find out your Office version.

The Office serial number, which is also commonly referred to as the product key, can’t be found out using this method. To find your Office product key, special additional tools from third-party providers are needed.

Find out the last used Office version of a document

In each document, Microsoft Office stores the version number of the Office program that was used to create and save the document. Based on this number, Office recognizes whether the document can be opened with a certain version and whether possibly incompatible macros or templates are included. However, this version number is not displayed directly in the properties of the document. Luckily, there’s a trick to finding it:

  1. First, create a backup of the document and change the file extension from .docx to .zip. If you do not see the file extension listed, you can have it displayed under “View” (Windows 8 to 10) or “Show” (Windows 11).
  2. Double click the zip file to open it.
  3. Open the docProps folder and launch the file app.xml.
  4. In the penultimate line under <AppVersion>, you will find the office version with which this file was saved.

Step 1: In explorer, switch to This PC and go to Program Files > Microsoft Office > Office. Step 2: Here you will find the subfolder OfficeXX with XX indicating the version number, for example 16 for Office 2016. Step 3: There may also be several folders with different version numbers if you have additionally installed macros or add-ins from other Office versions. In this case, search for the file WINWORD.EXEand right-click on it. SelectProperties from the context menu.
