Different Methods to Find My Windows 10 Product Key

Method 1: Finding the Product Key on Your Device

If your device came with Windows 10 preinstalled, then the product key should be stored somewhere on your system. It might be included in the BIOS or firmware of your computer. Here’s how to find it:

  1. Press "Windows Key + X" to open the Start menu and select "Windows PowerShell (Admin)" or "Command Prompt (Admin)."
  2. In the dialog box that appears, type the following command and press Enter:
    wmic path softwareLicensingService get OA3xOriginalProductKey
  3. Your Windows 10 product key will appear on the screen.

Pros:

  • Quick and easy to use, especially for newer devices
  • No need to install any third-party software

Cons:

  • May not work for older devices or systems that were updated from earlier versions of Windows
  • May not reveal the complete product key, only a partial one

Method 2: Finding the Product Key from the Registry

If your device came with an older version of Windows that you updated to Windows 10 or if you installed the operating system yourself, you can find the product key stored in the Windows Registry. Here’s how:

  1. Open Notepad or any text editor on your computer.
  2. Copy and paste the following code into the blank text document:
    Set WshShell = CreateObject("WScript.Shell")
    MsgBox ConvertToKey(WshShell.RegRead("HKLMSOFTWAREMicrosoftWindows NTCurrentVersionDigitalProductId"))
    Function ConvertToKey(Key)
    Const KeyOffset = 52
    i = 28
    Chars = "BCDFGHJKMPQRTVWXY2346789"
    Do
    Cur = 0
    x = 14
    Do
    Cur = Cur * 256
    Cur = Key(x + KeyOffset) + Cur
    Key(x + KeyOffset) = (Cur 24) And 255
    Cur = Cur Mod 24
    x = x -1
    Loop While x >= 0
    i = i -1
    KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
    If (((29 - i) Mod 6) = 0) And (i -1) Then
    i = i -1
    KeyOutput = "-" & KeyOutput
    End If
    Loop While i >= 0
    ConvertToKey = KeyOutput
    End Function
  3. Save the file with a .vbs extension.
  4. Execute the saved file with administrative privileges. A message box will appear, showing you a series of letters and numbers.
  5. This series of letters and numbers is your Windows 10 product key.

Pros:

  • No need to purchase any additional software
  • Reliable method that works for most Windows 10 devices

Cons:

  • May be difficult for non-technical users to execute
  • Can be time-consuming without a batch file or script

Method 3: Finding the Product Key with a Third-Party Tool

If you prefer not to use the Registry Editor or the Command Prompt, you can use a third-party tool to extract your Windows 10 product key for you. There are many such tools available online, including Belarc Advisor, ProduKey, and ShowKeyPlus. In this example, we will use ShowKeyPlus:

  1. Download and install the ShowKeyPlus software from its official website.
  2. Launch the program and select "Load Hive" in the menu bar.
  3. Enter the path of the Windows installation drive (usually "C:") and select the "Windows" folder.
  4. Select the "System32" folder and select the "config" folder.
  5. Select "SOFTWARE" and click "Open."
  6. The program will now extract the product key for you.

Pros:

  • Can be more straightforward than using the command prompt or registry editor
  • No need to be tech-savvy to extract the product key

Cons:

  • Some third-party tools may not be reliable or trustworthy
  • May be burdensome to install and use

5 FAQs About Finding My Windows 10 Product Key

Q1: What if my device didn’t come with Windows preinstalled?

A: If your device did not come with Windows preinstalled or you installed the operating system yourself, the product key should be included in the packaging or in the email receipt you received when you purchased the key. If you have lost these documents, you can try contacting Microsoft support or the retailer from whom you purchased the key.

Q2: Can I use the same product key on multiple devices?

A: If you’re having issues activating your Windows 10 product key, double-check that you’ve entered it correctly and that you’re not using an invalid or revoked key. If the issue persists, contact Microsoft support for further assistance.

Q5: Do I need a product key to upgrade to Windows 10?

A: If you’re upgrading from a previous version of Windows to Windows 10, you may not need a product key, as the upgrade process will automatically activate your operating system. However, if you’re performing a clean install of Windows 10 or installing it on a new device, you will need a valid product key to activate the system.
