Verifying Authenticity: How to Determine if Your Windows 10 Is Genuine or Counterfeit

How to Confirm Your Windows 10 Installation Is Legitimate

Not sure whether your copy of Windows 10 is the real deal? No worries — it’s easier than you might think. Microsoft offers some handy built-in tools that can help you verify authenticity. Just a quick visit to your Settings or a few keystrokes in the Command Prompt, and you’ll know whether your Windows is properly activated or just a lookalike.

How to Make Sure Your Windows 10 Is Authentic

Let’s get down to how you can check if your Windows 10 is genuine. It’s nothing complicated — just a few clicks and bits of info. If you’re not a tech whiz, don’t stress, it’s straightforward.

Checking via Windows Settings

Start by opening the Settings app. Hit the Windows key and click the gear icon, or press Windows + I. This is where you can find all system settings. From here, look for your activation status. It’ll tell you if your Windows has a proper licence.

Viewing Activation Status

Once in Settings, go to Update & Security (click Windows + I then select Update & Security). Here, you’ll find details about your updates and, most importantly, your Windows licence. Navigate to Activation in the sidebar. If it says “Windows is activated with a digital license”, you’re all set! But if it indicates activation issues or says it’s not activated, that’s a warning sign.

Quick Check Using Command Prompt

Prefer keyboard shortcuts? Open up the Command Prompt directly. Press Windows, type cmd or select Command Prompt, then run it as administrator (right-click and choose Run as administrator). Alternatively, press Windows + X and pick Windows Terminal (Admin). If you like using the Run window, press Win + R, type cmd, then hit Ctrl + Shift + Enter.

Running the Activation Check Command

In the Command Prompt window, type slmgr /xpr and press Enter. This command hits the licensing server and tells you whether Windows 10 is activated permanently. If it confirms that your licence is valid and active indefinitely, you’re all good. Any other message? Better do some more digging.

Additional Tips to Keep Your Windows Genuine

Always back up your important files before making big changes. Use File History or your preferred backup method — better safe than sorry!
Keep Windows updated to stay protected and get the latest features. Use Windows Update (Settings → Update & Security → Windows Update).
Install reputable antivirus software to guard against malware that might interfere with activation or security.
Buy your Windows licences from official sources or directly from Microsoft to steer clear of counterfeit copies.
To activate with a product key, go to Settings → Update & Security → Activation, then select Change product key. Or in Command Prompt, type slmgr /ipk YOUR-PRODUCT-KEY.
Digital licences activate automatically when you connect online, provided everything’s in order.

Frequently Asked Questions About Activation

What if my Windows 10 isn’t activated?

If you see a warning message, it might mean you’re running an unregistered or trial version. Try running slmgr /xpr again or check in Settings → Activation. There are steps you can take to resolve the issue.

Can I still get updates on non-genuine Windows 10?

You might get some updates, but you risk missing critical security patches. For safety’s sake, it’s best to run genuine Windows.

Can a pirated version of Windows be activated?

Generally, no. If your copy isn’t legitimate, you’ll need to buy a proper licence — either directly from Microsoft or an authorised retailer. Once you’ve got a valid key, activate via Settings or with slmgr /ipk YOUR-LICENSE-KEY in Command Prompt.

Does Microsoft detect fake copies of Windows?

Yes, they have systems to track counterfeit software. If detected, your access to updates and support may be restricted, and you might start seeing notices prompting you to buy genuine software.

Is using pirated Windows 10 legal?

Absolutely not. It’s against the law and Microsoft’s terms of service. Sticking with genuine software not only keeps you on the right side of the law but also ensures you get proper support and security.
