How to Check If Windows Is Genuine or Pirated Using CMD

Learn how to check your Windows activation status using the slmgr /xpr command and determine whether your installation is permanently activated.

Many PC users assume that because Windows says “Activated” in the Settings app, their copy is authentic and lifetime-licensed. However, shady repair shops and pirated ISO installers often use temporary KMS (Key Management Service) activators that expire every 180 days and require suspicious background servers. Here is how to verify your real license status in seconds.

Interactive Simulator: Testing SLMGR Commands

Click through the commands below to see what each command does and what the official Windows dialog output looks like:

Windows Script Host (SLMGR) Inspector
Command Prompt Utility
C:\Windows\System32> slmgr /xpr
Purpose: Checks the exact expiration date or permanent activation status.
Windows Script Host ✕
Windows(R), Professional edition:
The machine is permanently activated.
💡 Result: "The machine is permanently activated" means you possess a genuine, non-expiring license.

Alternative Method: Check Activation in Windows Settings

You can also verify digital license linking without the command line:

  1. Press Win + I to open Windows Settings.
  2. Go to System → Activation.
  3. Click on Activation state. A genuine installation will display: "Windows is activated with a digital license linked to your Microsoft account."

Frequently Asked Questions (FAQ)

Why does a technician's installation show a KMS expiration date?
Third-party computer repair shops sometimes use automated KMS scripts (like KMSAuto or MAS in unauthorized modes) to activate Windows quickly without purchasing a genuine retail or OEM key. These expire after 180 days unless reconnected to their server.
What happens when a 180-day volume KMS license expires?
Windows will enter non-genuine notification mode: your desktop wallpaper turns black, a permanent "Activate Windows" watermark appears in the lower-right corner, and personalization settings (themes, taskbar colors) become locked.
Can I convert a pirated or KMS Windows into a genuine license?
Yes. You do not need to reinstall Windows. Simply buy a genuine Windows product key from the Microsoft Store, go to Settings → System → Activation → Change product key, enter your key, and click Activate to convert it to a permanent digital license.
Is Windows 11 activation tied to my Microsoft account?
Yes! If you sign into Windows 11 with your Microsoft Account, your hardware ID and digital license are synced to your cloud account, making reactivation seamless even after replacing your SSD or reinstalling Windows.

Final Thoughts

Checking your Windows license takes less than five seconds with slmgr /xpr.

Ensure your PC displays “The machine is permanently activated” to enjoy uninterrupted security updates, cloud syncing, and genuine Microsoft support!
