How to activate Pre-installed Microsoft Office in Dell/Lenovo/HP and other OEM devices

Most of the computers these days are shipped with Microsoft Office pre-installed license. Some of the manufacturers offer Microsoft 365 Home or Personal 1-year subscription and some of them offer Microsoft Office 2019 Home and Student, Home and Business and Pro versions. For most of the users, the activation process is hassle-free. They just have to launch Word in the machine and right after launching, they see the banner which shows that the machine came with pre-installed Office license and after clicking on Activate button, they are asked to log in with their Microsoft account and after signing in, the license gets redeemed with their Microsoft account and Office gets activated on the device.
But there is a big confusion among the users and the OEM technicians about the activation process of Microsoft Office in the OEM devices. These devices are shipped with pre-installed Office 365 applications which are usually MS Store apps or installed with Office Deployment Tool. Now, this is where the confusion begins, the devices which are shipped with Office 2019 licenses, they also have Office 365 applications installed in them and to redeem the license of Office 2019 also, we have to use the Word application which is already installed with the package of Office 365. But out of the confusion, users uninstall Office 365 from the computer and I have seen that not only users, even the OEM support technicians also ask the users to uninstall Office 365 from the machine which is completely wrong. If you uninstall Office 365 from the machine, you might lose your Office 2019 pre-installed license also which is bound in the machine through the Windows registry.

So no matter what license you've got with the device, never uninstall the pre-installed Office 365 applications. Redeem your pre-install license with the Word app which got installed with the Office 365 suite and you would be able to redeem your license for Office 2019 successfully. Once the redemption process is completed, you can install the latest updates of Office and the pre-installed Office 365 would be changed into Office 2019 automatically after updates are installed. If the installation doesn't get changed automatically, you can uninstall Office 365 and installed your redeemed product through https://account.microsoft.com/services
Now some times, it happens that most of the users miss to redeem the license after launching Word and then the banner disappears from the machine. When they relaunch Word or any Office application, the pre-installed offer banner doesn't come up. To fix this issue, you would need to run the OEM Office Activation Troubleshooter from the link https://aka.ms/diag_97275 and running this troubleshooter would reset the pre-installed license to its default state. After running the troubleshooter, if you would launch Word, the activation offer banner would again pop-up on the screen which you can use to redeem your pre-installed license.
I hope this article clears your doubts about the activation of the pre-installed Office in OEM devices. Keep visiting for more tips and tricks.
