Frequently Asked Questions

Why does Office 2019 ask for activation after a factory reset?

A factory reset wipes your system's registry and installed programs. When you reinstall Windows and Office, the Microsoft activation server may see the fresh operating system as a new device, prompting you to verify your license again to prevent piracy.

What is an OEM license for Office 2019?

An Original Equipment Manufacturer (OEM) license is a version of Office that comes pre-installed on a new computer. It is permanently tied to the motherboard of that specific laptop and usually cannot be transferred to a different PC, though it should survive a reset if reactivated correctly.

How do I find out if my Office 2019 license is linked to my Microsoft account?

Go to account.microsoft.com and log in with your credentials. Navigate to the 'Services & subscriptions' tab. If your license is linked, Office 2019 will be listed there under your purchased products, meaning you can reinstall and activate it just by signing in.
