Where Is My Windows 10 Product Key on Lenovo?

When you purchase a Lenovo laptop or desktop with Windows 10 pre-installed, you may eventually need the product key—whether you're reinstalling Windows, upgrading hardware, or troubleshooting activation issues. So, where exactly is the Windows 10 product key on a Lenovo device?

Let’s break it down.

OEM Activation: Embedded in BIOS/UEFI

Most modern Lenovo laptops and desktops come with OEM (Original Equipment Manufacturer) versions of Windows 10. In these systems, the product key is not printed on a sticker. Instead, it's digitally embedded in the BIOS/UEFI firmware.

This digital license activates automatically when:

• You reinstall the same edition of Windows 10 (Home or Pro),

• You're connected to the internet,

• And you’re using the original Lenovo device.

In other words, you usually don’t need to enter the key manually—Windows detects it and activates on its own.

How to Find the Key Manually

If you still want to view your product key, you can do it through Command Prompt:

1. Press Windows + X and choose Command Prompt (Admin) or Windows PowerShell (Admin)

2. Type the following command: pgsqlCopyEditwmic path softwarelicensingservice get OA3xOriginalProductKey

3. Press Enter
   If your system has a digital license stored in the firmware, this command will display your 25-character product key.

Note: This method works only if your Windows key is an OEM key embedded in the BIOS.

What If the Key Doesn’t Show?

There are a few reasons why you might not see a key:

• You upgraded to Windows 10 from Windows 7 or 8—those upgrades may not show the key.

• You're using a digital license tied to your Microsoft account.

• The original installation used a volume license key, often used in enterprise or education environments.

In these cases, Windows activates via Microsoft’s servers based on hardware signature or account association, and you may not have a retrievable key.

Lost Your Key or Replacing the Motherboard?

If you've replaced your motherboard or your system can't detect the embedded key, you may need to manually activate Windows 10. In such situations, it’s important to have a genuine product key ready.

You can purchase an affordable and legal Windows 10 Pro key from trusted sources like GenuineSoftStore. They offer authentic digital licenses with fast delivery and support—ideal for Lenovo users who need a replacement or fresh installation key.
