How to Check if Your Windows 11 License is Genuine & Permanently Activated

Whether you recently purchased a new PC, upgraded your hardware, or bought an activation key online, confirming that your copy of Windows 11 is 100% genuine and permanently activated is essential. Fraudulent or temporary KMS volume licenses often expire after 180 days without warning.

In this guide, we break down the definitive command-line tools built into Windows to audit your activation channel, key type (Retail vs. OEM vs. Volume), and expiration status.

Method 1: Check Expiration Status with slmgr.vbs /xpr

The fastest way to verify whether your Windows license is temporary or permanent is through the Windows Software Licensing Management Tool (slmgr):

1. Press Win + R on your keyboard to open the Run prompt.
2. Type slmgr.vbs /xpr and hit Enter.
3. A Windows Script Host dialog will appear on your desktop within 2 seconds.

What the Result Means:

• "The machine is permanently activated": Congratulations! You have a genuine lifetime Retail or OEM license. It will never expire or require periodic server check-ins.
• "Volume activation will expire [Date]": Your computer is running an unauthorized KMS emulator or university/enterprise volume key that must connect to a remote server every 180 days. If the server drops, your PC will be deactivated.

Method 2: Inspect Detailed License Channel via slmgr.vbs /dlv

To inspect your exact product key channel, cryptographic activation ID, and partial product key:

1. Open Command Prompt or Terminal as Administrator (Win + X, select Terminal (Admin)).
2. Enter the following command:

   slmgr.vbs /dlv

3. A detailed diagnostic window will open. Check the following rows:
   • Product Key Channel: Should display Retail or OEM:DM. If it displays GVLK (Generic Volume License Key), it is a temporary batch key.
   • License Status: Must read Licensed.
   • Partial Product Key: Displays the final 5 characters of your active key.

Method 3: Settings Verification & Microsoft Account Link

To ensure your digital license is safely tied to your cloud account for easy hardware transfers:

1. Open Settings (Win + I) > System > Activation.
2. Expand the Activation state dropdown.
3. Confirm it reads: "Windows is activated with a digital license linked to your Microsoft account".

Frequently Asked Questions

What is the difference between Retail and OEM licenses?

A Retail license allows you to transfer Windows to a completely new PC or motherboard in the future. An OEM license is permanently bound to the first motherboard it activates on. Both provide genuine, lifetime Microsoft updates.

Can Windows deactivate itself after a hardware upgrade?

Replacing a graphics card, RAM, or SSD will not trigger deactivation. However, replacing the motherboard changes your hardware hash (HWID). If you have a Retail key, you can simply re-enter it or use the Activation Troubleshooter to transfer your license.
