Bought a Windows key and want to make sure it’s genuine? The good news is that Windows itself tells you. A genuine key activates directly with Microsoft and keeps your PC fully licensed. Here’s how to verify it in a couple of minutes — and what the warning signs of a problem look like.
The Simplest Test: Activation Status
A genuine, properly licensed key shows Windows as activated:
- Windows 11: Settings → System → Activation
- Windows 10: Settings → Update & Security → Activation
If it says “Windows is activated” (with a digital license or a product key), you’re properly licensed.
Verify with a Command (slmgr /dlv)
- Open Command Prompt as administrator.
- Type
slmgr /dlvand press Enter. - Check that License Status reads Licensed.
Warning Signs of a Problem
- An “Activate Windows” watermark in the bottom-right corner
- A “not genuine” or “your license will expire soon” message
- The key fails to activate, or Windows deactivates a short time later
- Personalization settings are greyed out
If you see these after entering a key, the key may be invalid, blocked, or already in use elsewhere.
Genuine Keys Get Updates
Because a genuine license is the same Microsoft software, your PC continues to receive Windows Updates normally. Updates are never blocked just because you bought your key from a reseller.
