How do I find my Windows product key?

Finding your Windows product key can be essential for reinstalling the operating system or for verification purposes. There are several methods you can use to find your Windows product key, depending on your situation:

1. Check the Original Packaging: If you purchased a boxed copy of Windows, the product key should be on a sticker inside the box or on the packaging itself.
2. Look for a Sticker on Your PC: If you bought a pre-installed version of Windows with your computer, the product key is usually on a sticker attached to your computer. Common locations include the bottom of a laptop or the back of a desktop tower.

3. Use the Windows Settings: For Windows 10 and 11, you can find the product key through the settings:

   • Go to Settings > Update & Security > Activation.
   • You might see the last five digits of your product key under the "Windows" section.
4. Third-Party Software: There are programs like Product Key Finder, Magical Jelly Bean Keyfinder, or Belarc Advisor that can retrieve your product key from the Windows registry.

5. Command Prompt: For advanced users, you can use the command prompt to find the product key:

   • Open Command Prompt as an administrator.
   • Enter the command: wmic path softwarelicensingservice get OA3xOriginalProductKey
   • The command will return your product key.

Remember, your product key is unique to your installation of Windows, so keep it secure.

Where can I locate the product key on my Windows computer if the original sticker is missing?

If the original sticker with your Windows product key is missing, there are still ways to locate it:

1. Check Documentation or Emails: If you purchased Windows digitally, check your email for the purchase confirmation, which should include the product key. If you have a physical receipt or any documentation, the key might be printed there.
2. Microsoft Account: If you signed into a Microsoft account during setup, the product key might be linked to your account. You can check this by going to the Microsoft website and signing in.

3. Windows Registry: You can retrieve your product key from the Windows registry:

   • Open the Registry Editor by typing regedit into the search bar and pressing Enter.
   • Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
   • Look for the value named BackupProductKeyDefault, which may contain your product key.
4. Third-Party Software: Use software like Product Key Finder or Belarc Advisor to automatically retrieve the key from the registry.

   • Open Command Prompt as an administrator.
   • Enter the command: wmic path softwarelicensingservice get OA3xOriginalProductKey
   • The command will return your product key.

These methods can help you recover your product key even if the original sticker is lost.
