Where can you find your Office product key?

Find on line with Microsoft account: If your Office was purchased and downloaded online, or associated with a Microsoft account, your MS Office product key can be found online.

Open Microsoft website, and login with your Microsoft account used to buy or activate Office. The Office serial key will be showed on your Office account page.

Check from email: If you downloaded your Office from an online store, you might be able to get the license key from the email receipt. Check your mail folder, if you haven't deleted it, you will find the key on it.

Printed on a sticker: If your Office program came with your computer, the license key might be printed on the Certificate of Authenticity sticker in your computer.

If came with a CD, card, or box, look for the sticker on the card or packaging.

Find from system registry: The Office serial key is stored on the hard drive where you install Office program. You can find it from the registry, but you can't read it normally, because it is encrypted with binary code.

Find the DigitalProductID from registry by this way: HKEY_LOCAL_MATHINE\Software\Microsoft\WindowsNT\CurrentVersion\DigitalProductID.

Check your MS Office serial key with VBScript

The serial keys are encrypted on registry, you can't read it normally, but you can retrieve it with product key tool or VBScript.
