How to Find Your Windows 10 and Windows 11 Product Key

Knowing your Windows product key can be essential if you need to reinstall your OS or activate it on a new device. In this guide, we'll explore different methods to locate the product key for Windows 10 and Windows 11.

Method 1: Using Command Prompt (CMD)

This is one of the simplest ways and doesn’t require any additional software:

  1. Press Win + R to open the "Run" dialog box.
  2. Type cmd and press Enter to launch the Command Prompt.
  3. In the Command Prompt, enter the following command and press Enter: 
    wmic path softwarelicensingservice get OA3xOriginalProductKey
  4. If the product key is stored in the BIOS or UEFI, it will be displayed on the screen.

Method 2: Using PowerShell

You can also quickly find the product key using PowerShell:

  1. Press Win + X and select Windows PowerShell (Admin).
  2. Enter the following command and press Enter: 
    (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
  3. The product key will be shown in the console.

Method 3: Checking the Windows Registry

Sometimes the product key can be found in the Windows Registry, though this method may not always be reliable:

  1. Press Win + R and type regedit to open the Registry Editor.
  2. Navigate to the following path: 
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
  3. Look for the BackupProductKeyDefault entry — this value is your product key.

Method 4: Using Third-Party Software

There are specific tools designed to help you find your product key, such as:

  • ShowKeyPlus: A free utility that displays product keys for Windows and Office.
  • ProduKey: A lightweight program from NirSoft that quickly retrieves installed product keys, including for Windows.

Download and run one of these tools, and it will display your product key without the need to execute any commands manually.

Method 5: Check the Sticker or Documentation

If you bought a computer with pre-installed Windows, the product key might be printed on a sticker attached to the device or included in the purchase documentation.
