So which should you pick
If you’re a home user: browsing the web, gaming, streaming, light productivity, you’ll likely be fine with Windows 11 Home. The Pro features will mostly go unused. TechPP+1
If you’re a power user, developer, IT professional, small business owner, or you need any of the advanced features above (domain join, BitLocker, virtualization, etc.), then Windows 11 Pro is the better choice.
If cost is a factor: the Home edition is cheaper, and unless you need the extras, it might be the more cost‑effective choice.
Windows Licence Key
Microsoft Windows License Key Types – Explained with Examples
Microsoft provides five main types of license keys for Windows (also applies similarly to Office). These are:
Retail (FPP)
OEM (Original Equipment Manufacturer)
Volume Licensing (KMS & MAK)
Digital License / Digital Entitlement
Microsoft Product Keys for IoT / Special Editions
1. Retail Key (FPP – Full Packaged Product)
What is it?
A Retail key is purchased by end users directly from Microsoft, Amazon, or a store. It gives full ownership of a license that is transferable to another device.
Key Features:
Can be moved to another PC (but only one active PC at a time)
You get official Microsoft support
Usually sold in a box or via digital download
Example:
You buy Windows 11 Pro from the Microsoft website or Amazon.
You build your own PC and activate it using the Retail key.
Later, you buy a new PC → uninstall the key from the old one → reuse the key on the new PC.
Command to verify:
..................
slmgr /dli
OEM Key (Original Equipment Manufacturer)
What is it?
An OEM key is pre-installed by PC manufacturers (like Dell, HP, Lenovo) and is locked to the hardware (specifically the motherboard).
Key Features:
Cheaper than retail
Non-transferable
Activation is automatic during reinstall (key is stored in UEFI/BIOS)
No support from Microsoft — only from the PC maker
Example:
You buy an HP laptop with Windows 11 Home pre-installed.
The OEM key is embedded in the system.
You reinstall Windows → it activates automatically.
You cannot move this key to another device.
Command to verify:
..................
slmgr /dli
Volume License Keys (MAK / KMS)
What is it?
Used by businesses, schools, and government to activate many computers at once. Two types:
a) KMS (Key Management Service)
Devices activate through a local KMS server.
Activation expires after 180 days and needs to be renewed (by reconnecting to the KMS server).
b) MAK (Multiple Activation Key)
A single key that can activate a fixed number of machines directly with Microsoft.
Good for offline activation or low-infrastructure environments.
Example:
A university uses KMS to activate all lab computers automatically.
A small business uses a MAK key to activate 25 PCs, with no ongoing server needed.
Command to verify:
..................
slmgr /dli
slmgr -dli
Digital License / Digital Entitlement
What is it?
A modern activation method where no product key is needed — activation is linked to:
Your Microsoft Account
Your hardware ID
Key Features:
Often used when upgrading from Windows 10 to 11
Auto-activates after reinstall if same edition is installed
Common in Windows 10/11 free upgrades
Example:
You upgrade your Windows 10 Home laptop to Windows 11 Home.
No key was entered — but it’s activated via your Microsoft account.
If you reinstall Windows later, it activates automatically when you sign in.
To check:
Go to:Settings → System → Activation
Look for:
“Windows is activated with a digital license”

slmgr /dli
slmgr -dli
