Activating your copy of Windows means that you get to receive all important system updates, which are vital for security. It also removes annoying prompts to activate your OS and allows you to enjoy personalization settings. But to activate your Windows installation, you need to input your product key. If you’re unsure where your product key is, learn how to find it.
Good to know: check out how to easily lock your Windows PC.
What Is a Product Key?
Microsoft uses an original equipment manufacturer (OEM) product key: a 25-character sequence of numbers and letters to verify and authenticate your copy of the system.
Windows 11 uses digital licenses for system activation, which doesn’t require you to enter the product key during clean installations and updates. But if an activation error occurs, you may need to manually enter the key.
However, most Windows 10 versions (except for Version 1511 and later) require a product key to activate. Listed below are a handful of options to retrieve your product key if you have a version of Windows that requires it.
1. Windows Command Prompt
You can find the product key in two locations:
- the PC’s packaging
- the Certificate of Authenticity that comes with the computer
If you no longer have the box or certificate, follow the directions below to use Command Prompt to retrieve the product key:
Right-click the Start button, and select “Run” from the WinX menu.

Type cmd
and press Ctrl + Shift + Enter to run the Command Prompt as an Administrator. Click “Yes” in the User Account Control confirmation dialog to grant administrator permissions.
Copy and paste the following to the command line, and press Enter. This will retrieve your product key from your PC’s system registry.

Cmd will display your Windows product key underneath.

2. With PowerShell
You can also use PowerShell to find your OEM license key if you prefer this command-line utility.
Launch the Run dialog, and type powershell
.
![Opening PowerShell using the Run utility in Windows.](https://www.maketecheasier.com/assets/uploads/2023/09/run-powershell.jpg)
Press Ctrl + Shift + Enter to run PowerShell as an administrator on your computer. In the User Account Control dialog box, click “Yes” to confirm administrator access.
Copy and paste this command into the new window, and press Enter.
powershell "(get-wmiobject -query ‘select * from softwarelicensingservice’).OA3xOriginalProductKey"

Wait for your Windows product key to be displayed in the command line.

3. Registry Editor
The Windows product key is stored inside the system registry. Basically, the commands used in the previous two methods are just retrieving the product key from the Windows registry file.
You can directly access your product key using the Registry Editor.
Launch the Run utility, type regedit
, then hit Enter.
![Launching the Registry Editor using the Run utility in Windows.](https://www.maketecheasier.com/assets/uploads/2023/09/run-regedit.jpg)
Allow administrator access in the User Account Control dialog box.
Click the address bar in the system registry, and paste the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
![Navigating to location in Registry Editor.](https://www.maketecheasier.com/assets/uploads/2023/09/registry-path.jpg)
Find and select “BackupProductKeyDefault” among the listed keys in the location.
Your Windows product key should be displayed in the corresponding row under the “Data” column.

4. Third-Party Key Finder
If you’ve opted to (re)install your Windows OS by yourself, you will need to use a retail license. You can typically find it in the following locations:
- Included in the box, for copies of Windows purchased through a retailer
- Confirmation email sent by the retailer after purchasing your Windows version
Should these boxes or emails no longer be accessible, using a third-party key finder may do the trick. One of the best software programs for this purpose is ShowKeyPlus – available on the Microsoft Store.
Install the app, and your product key should be displayed on the “Home” tab after launching the program.

5. Contact Microsoft Support
If none of the methods above works, contacting Microsoft’s representatives would be your best bet. Do this via the native Settings app on your PC.
Launch Settings by pressing Win + I. Go to “System -> Activation.”
![Navigating to the Activation section in Windows System Settings.](https://www.maketecheasier.com/assets/uploads/2023/09/activation-settings.jpg)
Click the “Get help” link.
![Clicking "Get help" for Windows activation.](https://www.maketecheasier.com/assets/uploads/2023/09/get-help.jpg)
Click the “Contact Support” button in the new window.
![Clicking the "Contact Support" button to get Microsoft support.](https://www.maketecheasier.com/assets/uploads/2023/09/contact-support.jpg)
Under “Products and services,” select “Windows” from the drop-down list. Click “Confirm.”
![Selecting "Windows" from the Products and services dropdown in the Get Help window.](https://www.maketecheasier.com/assets/uploads/2023/09/product-services.jpg)
Click on “Provide your phone number and a support agent will call you” if you want to talk to an agent live. Alternatively, click on “Product Activation for Windows,” and chat with a support agent.
