Many times you might want to change the product key of Office suite installed in your system. It might be because your product key expired and you got a new one or it might be because you installed Office using pirated key and now you want to change the product key with a genuine one.
To change the product key you’ll have to uninstall the Office suite from your system and then reinstall it.
But here is a small and simple tutorial which will help you in changing the product key without uninstalling the Office.
