What Is a Product Key?
A Product Key is the traditional 25-character code used to activate Microsoft software.
How It Works
-
You manually type the 25-digit key during installation.
-
The activation connects directly to Microsoft servers.
-
If the product key is valid and unused, the system activates instantly.
Where Product Keys Are Commonly Used
-
Older versions of Windows (7, 8.1, early Windows 10)
-
Office 2016, Office 2019 retail versions
-
Boxed software or physical purchases
-
Cheap OEM licenses sold by resellers
Advantages
-
Portable – you can install and activate on new hardware (retail keys).
-
Works offline initially, activation completes once connected.
Disadvantages
-
Can be lost, shared, or misused by previous owners.
-
Some vendors sell invalid or recycled keys.
-
OEM keys usually activate only on one device permanently.
What Is a Digital License?
A Digital License (also called digital entitlement) is Microsoft’s modern activation method introduced with Windows 10 and used fully in Windows 11.
How It Works
-
The license is automatically linked to your copyright.
-
No product key is entered.
-
When you reinstall Windows or change hardware, your copyright re-activates the device.
Advantages
-
No product key needed – activation happens automatically.
-
Safer, because the license is tied to your digital identity.
-
Easier to restore after reinstalling Windows or replacing your hard drive.
-
Ideal for laptops and modern PCs.
Disadvantages
-
Requires a copyright.
-
Major hardware changes may require reactivation support.
