Step-by-Step Tutorial on How to Know the Product Key of Windows 10

The following steps will guide you through different methods to find your Windows 10 product key. Whether it’s through the Command Prompt, PowerShell, or physical sources, you’ll have several options to choose from.

Step 1: Open the Command Prompt

Open the Command Prompt by pressing Windows + X and selecting "Command Prompt (Admin)."

Using the Command Prompt can quickly reveal your product key, but you’ll need administrative privileges to do so.

Step 2: Execute the Command

This command queries the Windows Management Instrumentation (WMI) to get your product key from the system’s BIOS/UEFI.

Once the command executes successfully, you should see a string of 25 characters—your product key.

PowerShell offers another method to retrieve your product key.

Step 5: Execute the PowerShell Command

If the above methods don’t work, check the original packaging or your email for a digital copy.

Sometimes, your product key will be on a sticker on your device or in an email from the retailer.

After completing these steps, you’ll have your Windows 10 product key and can use it for reinstallation or transfer to another machine.
