Microsoft Licensing Models Explained: OEM, Retail & Volume (2025 Guide)

OEM License: Affordable but Fixed
When you buy a brand-new PC from brands like Dell, Lenovo, or HP, it usually comes with Windows pre-installed.
That Windows version is licensed under what’s called an OEM license , short for Original Equipment Manufacturer .
What Makes OEM Unique?
An OEM license is created for one computer, just one. It’s locked to the hardware , specifically the motherboard.
If your motherboard breaks or you build a new PC, that license doesn’t follow you. It stays with the original machine.
The main benefit here is cost. Since manufacturers buy these licenses in bulk, the price is low. That’s why you’re not billed separately for Windows when you buy a new laptop; it’s bundled in.
Who Should Use an OEM License?
If you’re someone who:
- Just bought a new laptop or desktop
- Doesn’t plan on building your own system
- Doesn’t need to transfer the operating system to another PC
Then OEM is probably all you need.
Pros of OEM:
- Cost-effective for new computer buyers
- Comes pre-installed and ready to go
- Great for people who never tinker with their setup
But Be Aware:
- You can’t move it to another PC
- No direct support from Microsoft, you’ll deal with the computer brand for help
Retail License: Full Ownership, Full Flexibility
Now imagine you’re building your own PC or you like to upgrade your hardware every couple of years. In that case, a Retail license is your best friend.
This license is the most flexible option of all. You buy it either in a physical box (yes, they still exist) or more commonly now, as a digital download from Microsoft or a verified seller.
Why Go Retail?
Because you own it. If you upgrade your PC, you can legally transfer that same license to your new machine. This is especially helpful if you’re investing in powerful custom hardware.
Who Should Choose a Retail License?
You should, if you:
- Build or upgrade your PCs
- Want control over where and how your OS is installed
- Don’t want to buy a new license every time your computer changes
Retail License Highlights:
- Transferable to another PC
- You get official Microsoft support
- Works as a standalone product with no previous version required
The Catch?
- It’s more expensive than OEM
- You’ll need to install and activate it yourself (not hard, but worth knowing)
Volume License: Made for Organizations
Let’s say you’re an IT admin at a school, a startup, or a government office. You need to install Windows across dozens, maybe hundreds, of computers. Buying a separate license for each? Not practical.
That’s where Volume Licensing comes in.
What Is Volume Licensing?
It’s a way for organizations to license Microsoft software for multiple machines under one agreement. You get either a single activation key (called a MAK ) or use a KMS (Key Management Service) server to manage all activations centrally.
Who Uses It?
- Corporations
- Schools and universities
- Nonprofits and government agencies
Why Organizations Love It:
- Bulk pricing makes it cheaper as you scale
- IT admins can create a custom Windows setup and deploy it everywhere using re-imaging rights
- You can bundle in Software Assurance , which gives access to upgrades, support, training, and more
Important to Know:
- These licenses aren’t tied to an individual or machine but to the organization.
- Not ideal for single users or home setups

Wrapping It All: Picking the Right Microsoft License for You
Let’s be real, Microsoft licensing models aren’t the most exciting topic. But choosing the right one can save you money, protect your system, and avoid legal headaches later.
If you’re buying a new machine and just want it to work out of the box? OEM is perfect.
If you build PCs or want the freedom to take your license with you? Retail is the smarter, long-term bet.
And if you’re managing dozens of machines for a business or institution? There’s no better option than Volume Licensing .
Whatever your use case, understanding these models means you’re now in control, no more guessing, no more getting stuck with a license that doesn’t fit.
