What Is a Digital License vs Product Key? Windows & Office Explained (2026)

Digital License vs Product Key: Why It Matters

When you buy or activate Windows or Microsoft Office, you'll encounter two types of licenses: a digital license and a product key. Many users don't know the difference — and that confusion can cause real problems when upgrading hardware, reinstalling Windows, or troubleshooting activation errors.

This guide explains both methods clearly, how to check which one you have, and what it means for transferring or reinstalling your software.

What Is a Product Key?

A product key (also called a license key or activation key) is a 25-character alphanumeric code in the format XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. It's the traditional method of activating Microsoft software.

When you enter a product key, Microsoft's activation servers verify it and activate your copy of Windows or Office. The key is tied to your installation but can generally be used to reinstall or transfer the software (depending on the license type).

Where you find a product key:

• In your email confirmation after purchasing online (e.g., from LicenGold)
• On a sticker on the box or Certificate of Authenticity (COA) for retail copies
• On a sticker on your PC (for OEM licenses)
• In your Microsoft account order history

What Is a Digital License?

A digital license (formerly called "digital entitlement") is a modern activation method that links your Windows license directly to your device's hardware — specifically your motherboard's unique hardware ID — and optionally to your Microsoft account.

With a digital license, there is no product key to enter. Windows activates automatically when it detects the hardware it was originally activated on. If you've linked it to your Microsoft account, you can also reactivate it after a hardware change.

How you get a digital license:

• Upgrading from Windows 7/8/10 to Windows 10/11 via Microsoft's free upgrade offer
• Buying a new PC with Windows pre-installed (OEM digital license)
• Purchasing Windows through the Microsoft Store
• After activating Windows with a product key — Microsoft may issue a digital license linked to your hardware

Key Differences: Digital License vs Product Key

Feature	Product Key	Digital License
Format	25-character code	No visible key — hardware-linked
Stored where	Email, sticker, or account	Microsoft's servers + your hardware ID
Activation method	Manual key entry	Automatic (hardware detection)
Transferable	Depends on license type (Retail = yes, OEM = no)	Depends on original license type
Survives reinstall	✅ Yes (re-enter key)	✅ Yes (auto-detects hardware)
Survives hardware change	✅ Yes (Retail) / ❌ No (OEM)	✅ Yes if linked to Microsoft account (Retail)

How to Check Which Type of License You Have

For Windows

Open Command Prompt as Administrator and run:

slmgr /dli

Look for the License Type field in the output:

• "Retail" — you have a transferable Retail product key or digital license
• "OEM" — your license is tied to this specific machine
• "Volume" — enterprise/volume license

You can also check in Settings → System → Activation. If it says "Windows is activated with a digital license" or "Windows is activated with a digital license linked to your Microsoft account", you have a digital license.

For Microsoft Office

Open any Office app (Word, Excel, etc.), go to File → Account. Under "Product Information", you'll see your activation status. Office licenses are almost always product key-based for standalone versions (Office 2021, 2024) or subscription-based for Microsoft 365.

Digital License and Microsoft Account: Why You Should Link Them

If you have a digital license, linking it to your Microsoft account is strongly recommended. Here's why:

• ✅ Easy reactivation after hardware changes — use the Activation Troubleshooter to reactivate on new hardware
• ✅ No need to remember a product key — your license is stored in the cloud
• ✅ Reinstall Windows anytime — just sign in with your Microsoft account and Windows activates automatically

To link your digital license: go to Settings → System → Activation → Add a Microsoft account.

Product Keys for Windows: Retail vs OEM

Not all product keys are equal. The type of key determines whether you can transfer your license:

• Retail key: Fully transferable. You can move it to a new PC by deactivating it on the old one. This is what LicenGold sells — see our Windows 11 Pro Retail key and Windows 10 Pro Retail key.
• OEM key: Tied to the first PC it's activated on. Cannot be transferred. Typically found on stickers on pre-built PCs.

What Happens to Your License When You Reinstall Windows?

• Digital license: Windows automatically reactivates after reinstall on the same hardware. No key needed.
• Product key (Retail): Enter your key during or after installation to reactivate.
• Product key (OEM): Should reactivate automatically on the same hardware. If not, use the Activation Troubleshooter.

Microsoft Office: Product Key Activation Explained

Microsoft Office standalone versions (Office 2021, Office 2024) use product key activation. Here's how it works:

1. Purchase your Office license and receive your 25-character product key
2. Download Office from setup.office.com
3. Sign in with your Microsoft account and enter your product key
4. The key is linked to your Microsoft account for future reinstalls
5. Install Office on your PC — it activates automatically

• Microsoft Office 2024 Professional Plus – Lifetime License
• Microsoft Office 2021 Professional Plus – Lifetime License

How to Recover a Lost Product Key

If you've lost your Windows product key, you have several options:

• Check your email from when you purchased the key (e.g., your LicenGold order confirmation)
• Use a key retrieval tool like ProduKey or ShowKeyPlus to extract the key from your current Windows installation
• Check your Microsoft account at account.microsoft.com under Services & Subscriptions

Frequently Asked Questions (FAQ)

Do I need a product key if I have a digital license?

No — with a digital license, Windows activates automatically based on your hardware ID. You don't need to enter a product key. However, if you change your motherboard, you'll need to use the Activation Troubleshooter with your Microsoft account to reactivate.

Can I find my digital license key?

No — digital licenses don't have a visible key. They're stored on Microsoft's servers linked to your hardware ID and/or Microsoft account. This is by design.

Is a digital license better than a product key?

Both have advantages. Digital licenses are more convenient (automatic activation, no key to lose). Product keys are more portable — especially Retail keys, which can be transferred to a new PC. For maximum flexibility, a Retail product key linked to your Microsoft account gives you the best of both worlds.

What happens to my digital license if I change my motherboard?

A motherboard change can break automatic activation since the hardware ID changes. If your digital license is linked to your Microsoft account, use Settings → System → Activation → Troubleshoot to reactivate. If it was an OEM digital license, you may need to purchase a new license.

Can I use the same product key on two computers?

No — a standard Windows or Office product key is licensed for one PC at a time. If you need multiple activations, check our multi-PC licenses: Windows 11 Pro – 5 PC License or Office 2024 – 5 PC License.

How do I know if my Windows key is genuine?

A genuine key will activate successfully through Microsoft's servers. You can also check your activation status in Settings → System → Activation. For tips on spotting fake keys, read: How to Tell If Your Microsoft Key Is Genuine (And Not a Scam).
