I'm sure it's happened to you. You are looking for a Windows license and, suddenly, you find prices that seem a joke. While on Microsoft's official website they are around 100 or 150 euros, on other pages they appear for less than 20 euros.
And of course, the question is inevitable: How is it possible that Windows licenses are so cheap?
Official vs. third party licenses 🏷️
Microsoft sells official licenses through its store and authorized distributors. These are known as retailThe 100% is fully valid, supported and with the peace of mind of being 100% in compliance with the law.
The licenses you see on unknown sites usually belong to other types: OEM, volume keys or even recycled licenses of old equipment.
The price difference is not a coincidence, but the result of a parallel market that feeds on these variants.
What are OEM licenses ⚙️
The OEM (Original Equipment Manufacturer) licenses are the ones that come pre-installed when you buy a new computer.
They are designed to be used only on that specific machine and should not be resold separately.
When you see an OEM Windows key at 10 or 15 euros, it is most likely to come from batches that some company never used or that have been extracted from decommissioned equipment.
The mystery of the volume keys 🗝️
Microsoft also offers to companies, universities and public administrations the so-called volume licenses.
With them, an organization can activate hundreds or thousands of devices with the same master code.
The problem is that these keys, sometimes, end up leaking and end up on resale sites.
You buy one of those keys thinking it's legal, but in reality Microsoft could block it at any time.
Recycled licenses ♻️
There is also a market for recycled licenses.
In the European Union, the law allows software to be resold as long as the original license is not being used on another computer.
This means that if a company changes all its computers, it can sell its old licenses to an intermediary, who then offers them to the public.
In theory it is legal, but there is an important detail here: not all the sites that sell them can prove their origin.
Why they are so cheap on some portals 🌐.
When you go to websites such as G2A, eBay or similar sites, the keys appear at ridiculous prices.
This occurs because are not official distributors but secondary marketplaces where anyone can offer code for sale.
In many cases, these keys come from:
- Surplus OEM lots.
- Filtered business volumes.
- Recycled licenses without clear guarantees.
The low price is tempting, but it also reflects the lack of official support and the risk of running out of a functional operating system.
Are cheap Windows licenses safe? ⚠️
Here is the key point.
A reused OEM license can run smoothly for years, but if Microsoft detects misuse, the key may deactivate out of the blue.
The volume ones are even more risky, because they usually have a short life before being blocked.
At best, you save money. At worst, your Windows stays not activated and you face annoying screens, limitations and security risks.
What the law says 📜
In Europe, the resale of used software is legal as long as the license was legitimately acquired and is no longer active on another device.
The Court of Justice of the European Union even ruled on the matter in 2012, endorsing the circulation of second-hand licenses.
The problem is that many sellers do not comply with these conditions and take advantage of the consumer's knowledge gap.
How to know if a license is reliable 🔎
If you want to avoid disappointment, pay attention to these details before you buy:
- Verify if the vendor is authorized by Microsoft.
- Check if they offer legal invoice with VAT.
- Read reviews from other users on independent portals.
- Be wary of keys at ridiculously low prices.
In case of doubt, the wisest course of action is to opt for the official Microsoft Store or recognized distributors such as Amazon, PcComponents or similar.

Benefits of paying for an official license 💳
Although more expensive, an official license brings with it several benefits:
- Guaranteed technical support.

In the end, cheap can be expensive if your operating system is disabled just when you need it most.
So, are cheap licenses worth it? ⚖️
