How to Activate Microsoft Office 2016 without Product Key

So you need to activate Office 2016 but have no product key? Now in this page I’m going to show two ways of how to activate Office 2016 without product key. And I will take Microsoft Office Professional Plus 2016 in Windows 10 as an example. If you are using other versions of Office 2016 on other Windows, the two ways also work.


Way 1: Activate Office 2016 with KMSpico activator

If you got free Microsoft Office Professional Plus 2016 installed without product key, you can activate it by using the special KMSpico activator tool.

KMSpico activator contains Install version and Portable version, either of which can help activate Office 2016 without product key. You can use kmspico activator office 2016 keyword to search in Google search engine or any other search engine and then download any one version of the KMSpico activator. Before downloading, you’d better temporarily disable Anti-virus program on your computer in case it intercept the downloading of any third-party program. Then use this tool to activate Office 2016.

Part 1: How to use KMSpico Install version

Step 1: After KMSpico Install is downloaded, double click to run the KMSpico_setup.exe file. If prompted with User Account Control dialog, confirm it.

Tips: Your downloaded KMSpico file may not indicate whether it’s Install version or Portable version. Never mind. You just need to find the KMSpico_setup.exe or KMSELDI.exe file.

Way 2: Activate Office 2016 with product key finder

If you ever installed genuine Office 2016 with product key but later lost or misplaced the product key, you can retrieve the product key by using a Product Key Finder tool. Then use the retrieved key to activate Office 2016.
