Most pieces of commercial software come with some form of protection to deter unauthorized copying and installation. Although software makers use different methods to achieve this goal, one common approach involves asking the user to type in a product key or serial number, which is the case for both Microsoft Windows and Office 365.

This string of letters and/or numbers is a unique identifier that the software decodes to verify that your copy is legal. It’s required to authorize the software’s installation and your eligibility for product support, so it’s important to know where it is and how to access it.

 

A Windows product key is a 25-character code used to activate Windows.

It looks like this:

PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

  • Most software you buy directly from Microsoft Store as a digital download, like Office, Windows, and Xbox games, can be downloaded, installed, or reinstalled in order history. Find the software and then select Product key/Install.( same for office 365 and windows key)
  • If you have a digital gift card that’s good for a game or app, you must redeem it first.
  • If you bought your Microsoft software from a third-party website, you’ll need to get download and product key info from them.

 

Where to find your product key depends on how you got your copy of Windows:

  • From an authorized retailer. The product key is on a label or card inside the box that Windows came in.
  • A new PC running Windows. The product key is preinstalled on your PC, included with the packaging the PC came in, or included on the Certificate of Authenticity (COA) attached to the PC.
  • A digital copy from a Microsoft website. The product key is in the confirmation email you received after buying it. Or, it may be distributed as a digital license if you bought Windows 10, in which case it doesn’t include a product key.
  • Free upgrade to Windows 10. If you upgraded to Windows 10 for free from Windows 7 or Windows 8.1, you should have a digital license instead of a product key.

 

If you bought a retail copy of Microsoft Windows or Office, the first place to look is in the disc jewel case. Retail Microsoft product keys are usually on a bright sticker located inside the case with the CD/DVD, or on the back. The key consists of 25 alphanumeric characters, usually split into groups of five.

If your computer came preloaded with Microsoft Windows, the software product key is usually on a multicolored, Microsoft-branded sticker on your PC case. For Microsoft Office, you can find the sticker on the installation disc that accompanied the computer. If all else fails, you will need to contact Microsoft to obtain a replacement key.

Typically you can find your Microsoft Windows product key on a sticker attached to your PC.

Windows 10

With Windows 10 Microsoft introduced a new method for authenticating the operating system called a digital entitlement, but it doesn’t apply to all Windows 10 PCs.

Basically, you have a digital entitlement if you upgraded your PC from Windows 7 or 8.1 for free. You will also have a digital entitlement if you paid for a Windows 10 upgrade via the Windows Store, or did a fresh install of Windows 10 and then paid for it via the Windows Store.

If, however, you obtained Windows 10 by buying a new PC, buying a Windows 10 installation DVD, or buying a digital copy of Windows 10 from a retailer that’s not the Windows Store then you have a traditional product key, not a digital entitlement.

What a digital entitlement means

If your PC has a digital entitlement, Microsoft keeps a record of your right to run Windows 10 on its servers. The good thing about this system is there’s no product key to lose. If you ever need to do a fresh install from a USB drive, for example, you will not have to activate your PC. Instead, after the reinstall Windows will activate seamlessly in the background within a few hours (or at worst a few days).

what-digital-entitlement-means

The one thing to keep in mind is that your digital entitlement is based around your system configuration. If you change too many components at once and then try to reinstall Windows 10 you may run into problems. This is a rare issue, but it’s something to keep in mind if you are planning on swapping out your hard drive or SSD and hope to do some other upgrades at the same time.

It would be better, for example, to do the HDD to SSD swap first, reinstall Windows 10, and once it’s activated take care of the other component upgrades. Otherwise, you might be putting in a call to Microsoft’s robo-activation line.

That said, major upgrades like swapping out your motherboard are almost certainly guaranteed to require a call to Microsoft for activation.
