If you’ve ever activated Windows or checked your activation status, you’ve probably seen one of two things: a 25-character product key or a message saying your device has a digital license. Both get your Windows activated, but they work differently — and understanding the distinction matters when you’re troubleshooting activation issues, reinstalling Windows, or moving your license to a new computer.

Let me break down what each one actually means and help you figure out which type you’re working with.
What Is a Product Key?
A product key is the traditional method of activating Windows. It’s that 25-character code formatted like XXXXX-XXXXX-XXXXX-XXXXX-XXXXX that you’ve probably typed in at some point during a Windows installation.
You’ll find product keys in a few places:
- Retail purchases: On a card inside the box or printed on a sticker
- OEM computers: Sometimes on a Certificate of Authenticity sticker on the device itself (though this is less common now)
- Volume licensing: Provided through your organization’s licensing portal
- Email confirmations: If you purchased Windows online from Microsoft or an authorized reseller like MCAKey
When you enter a product key, Windows contacts Microsoft’s activation servers to verify it’s legitimate and hasn’t been used on more devices than allowed. Once verified, you’re activated.
Quick Answer
A product key is a 25-character code you enter manually to activate Windows, while a digital license ties your activation to your Microsoft account and hardware with no code required. To check which one you have, open Settings > System > Activation — you’ll see either “Windows is activated with a digital license” or “Windows is activated with a product key.” Digital licenses offer easier reinstallation since Windows reactivates automatically when you sign in, but product keys give you a portable code you can reference and potentially transfer to another PC.
What Is a Digital License?
A digital license (previously called a “digital entitlement”) ties your Windows activation to your Microsoft account and your device’s hardware profile rather than to a typed-in key. There’s no code to enter or keep track of — the activation lives in Microsoft’s servers and recognizes your specific computer.
You get a digital license when you:
- Upgrade from a genuine copy of Windows 7 or 8.1 to Windows 10 or 11 (back when the free upgrade was offered)
- Purchase Windows from the Microsoft Store while signed into your Microsoft account
- Buy a device with Windows pre-installed (the license is embedded in the firmware)
- Activate with a product key and then link it to your Microsoft account
The beauty of a digital license is that if you ever need to reinstall Windows on the same hardware, you don’t need to hunt down a product key. Windows automatically reactivates once you’re connected to the internet and signed into your Microsoft account.
How to Check Which Type You Have
This takes about 30 seconds:
- Press Windows + I to open Settings
- Go to System > Activation
- Look at your activation status
You’ll see one of these messages:
- “Windows is activated with a digital license” — You’re using a digital license
- “Windows is activated with a digital license linked to your Microsoft account” — Even better, it’s tied to your account for easier recovery
- “Windows is activated with a product key” — You’re using a traditional product key
Why Does This Matter?
For day-to-day use, both activation methods work identically. But the differences become important in a few scenarios:
Reinstalling Windows: With a digital license linked to your Microsoft account, reinstallation is painless — just sign in and you’re done. With a product key, you’ll need that key handy or Windows won’t activate.
Replacing hardware: If you swap out your motherboard (the main component Windows uses to identify your PC), a digital license linked to your Microsoft account gives you the best chance of reactivating without buying a new license. You can use the Activation Troubleshooter and select “I changed hardware on this device recently.”
Transferring to a new PC: Retail licenses can be transferred to a different computer (after removing them from the old one). OEM licenses — whether digital or key-based — are typically locked to the original device.
Quick Tips
- Link your digital license to your Microsoft account if you haven’t already. It’s under Settings > Activation > Add a Microsoft account. This gives you a safety net if you ever need to reactivate.
- Keep product keys somewhere safe if that’s what you’re using. I recommend a password manager or at minimum a photo stored in cloud storage.
- Know your license type before major hardware changes. An OEM license might not survive a motherboard swap, while a retail license should.
Bottom Line
Both product keys and digital licenses accomplish the same goal — proving you have a legitimate copy of Windows. Digital licenses are more convenient since there’s nothing to lose or type in, while product keys give you a tangible code you can reference. Most newer PCs come with digital licenses embedded, but if you’ve purchased a standalone Windows license, you likely have a product key.

Frequently Asked Questions
Will I lose my Windows activation if I replace my hard drive?
No, replacing your hard drive or SSD won’t affect your activation status. Windows identifies your PC primarily through the motherboard, so storage upgrades are safe. After reinstalling Windows on the new drive, your digital license will reactivate automatically, or you can re-enter your product key.
Can I use my Windows product key on a different computer?
It depends on your license type. Retail product keys can be transferred to a new PC after you deactivate or uninstall Windows from the old one. OEM keys — the kind that come pre-installed on branded PCs from Dell, HP, Lenovo, etc. — are permanently tied to the original motherboard and cannot be legally transferred.
What happens to my digital license if I’m not signed into a Microsoft account?
Your digital license still works, but it’s only linked to your hardware profile. If you later replace major components like the motherboard, you won’t have the option to use the Activation Troubleshooter to recover your license. Linking to a Microsoft account takes 30 seconds and gives you a recovery path.
How do I find my Windows product key if I need it for reinstallation?
Check your original purchase email, the packaging your software came in, or your Microsoft account purchase history at account.microsoft.com. For OEM PCs, the key may be embedded in the UEFI firmware and Windows will detect it automatically during installation — you won’t need to enter it manually.
