Most software programs require a product key as part of the installation process, including the latest version of Microsoft Office. If you lose your Microsoft Office product key, you’ll need to find it before reinstalling it.
Microsoft Office product keys are encrypted in the Windows registry, making it almost impossible to search them manually. Once you find the correct registry key, you’ll find a string of numbers, but you’ll find encrypted text instead of the work Office product key you can enter.
Microsoft Office 2016, like all versions of Office and most other programs you pay for, requires that you enter a unique Product Key during the installation process, proving, to a point, that you own the software.
So what do you do if you need to reinstall the program but you’ve lost this important, 25-digit installation code? If you’re familiar with Product Keys and how they work, you might assume that the Microsoft Office 2016 Product Key is stored, encrypted, in the Windows Registry, like older versions of Office and most other programs do.
Find Office 2016 keys in a document or email
1. If you purchased Microsoft Office 2016 in a box with a CD, or purchased a product card (digital download) from a retail store, the product key will be with the actual purchase – on the product card, on the label, in the manual, or In the manual, or on the disc sleeve.
2. If you purchased these versions of Office online from Microsoft, your product key will be stored online in your Microsoft account and/or in your email receipt.
3. If you pre-installed Microsoft Office 2016 on your computer, the product key should be printed on a holographic sticker attached to your computer.
If you previously registered and activated a copy of Microsoft Office 2016, you will be happy to know that Microsoft has stored it for you and will show you your original product key.
Here’s what you need to do to see it:
1. Log in to your Microsoft office: My Account page.
2. Click or click “Install” on the CD.
3. On the next loaded page, click or click “I have a disc” and then click “View Product Key”.
If possible, record the Microsoft Office 2016 product key and keep it in a safe place.
Another option, that you may or may not have the most luck with, is to contact Microsoft directly to ask for a replacement key. Microsoft obviously isn’t going to just trust that you bought Microsoft Office and read you a valid Product Key over the phone. You’ll need to find whatever proof of purchase you can find and have it ready before calling.
