Sellers to Avoid
We also tested several other platforms and recommend avoiding these:
eBay or Facebook Marketplace
Too many reused or non-working keys. Refunds are unreliable.
AliExpress or Wish
Often sells counterfeit or blocked keys. Many are volume licenses from schools or corporations.
Random websites offering $5 keys
Many are fake or phishing sites. Even if you get a working key, there’s a high chance of deactivation.
Understanding License Types
Not all Windows keys are the same. Here’s a breakdown:
| Type | Transferable | Typical Source | Common Price Range | Best Use Case |
|---|---|---|---|---|
| OEM | No | PC builders, resellers | $10–$20 | One-time personal activation |
| Retail | Yes | Microsoft, trusted stores | $25–$60 | Upgrades, future device use |
| Volume | No (and risky) | Enterprises, schools | $2–$15 | Avoid — often resold illegally |
Frequently Asked Questions
Is it legal to use OEM keys bought online?
Technically, yes. In many countries, it’s legal to buy and use OEM licenses for personal use. Microsoft’s terms may restrict their resale, but that doesn’t make it a criminal offense for buyers.
Will I still get Windows updates?
Yes. Once activated, your Windows installation will function just like a retail copy—including regular security and feature updates.
What happens if the key doesn’t work?
Most reputable sellers (like SFTKEY or Keysfan) will issue a replacement. Always save proof of purchase and payment confirmation.
How to Activate a Windows 11 Key
