Trying to find your Windows 11 product key can be confusing, especially if Windows came preinstalled on your PC. You might expect to find a 25-character code somewhere in Settings, but that is not always how Windows activation works.
Windows 11 can be activated with either a 25-character product key or a digital license. A digital license does not require you to enter or manually retrieve a product key. There are several ways to check what type of Windows license you have and, when available, retrieve the product key.
In this guide, we’ll walk through the most useful methods, including Windows Settings, Command Prompt, PowerShell, your PC’s UEFI firmware, purchase records, packaging, and Microsoft account information.
Finding Your Windows 11 Product Key [Full Guide]
Before jumping into the methods, there’s one important distinction to understand. Your PC may be activated without having a product key that Windows can display.
A product key is a 25-character code in this format: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. A digital license, on the other hand, is an activation method associated with your device and, in many cases, your Microsoft account.
So, if you don’t find a key, that doesn’t automatically mean Windows isn’t properly licensed.
1: Check Windows Activation Status
The first thing you should do is check how Windows 11 is activated. This takes only a few seconds and can tell you whether looking for a product key is even necessary.
Go to Start > Settings > System > Activation. Look at the Activation state section. If Windows says it is activated with a digital license, your PC may not have a retrievable retail-style product key. If it says the digital license is linked to your Microsoft account, that’s even more useful if you ever need to reactivate Windows after certain hardware changes.
If you see an activation problem instead, select the available troubleshooting option and follow the instructions Windows provides. Don’t immediately purchase another license just because you can’t see a product key.
2: Find an OEM Product Key Using Command Prompt
If Windows 11 came preinstalled on your computer, there’s a good chance the original OEM product key is embedded in the device’s UEFI firmware.
To check for it, open Start, type Command Prompt, right-click Command Prompt, and select Run as administrator.
Enter the following command:
wmic path softwarelicensingservice get OA3xOriginalProductKey
Press Enter. If your computer has an OEM key stored in its firmware, Windows may display the 25-character key.
This method is particularly useful on PCs that originally shipped with Windows. Microsoft’s OEM documentation explains that manufacturers can inject Windows product keys into a computer’s firmware through the OA 3.0 process.
If the command returns a blank result, don’t panic. It can simply mean that there isn’t an OEM product key stored in the firmware, or that your Windows activation uses a different licensing method.
3: Check the Product Key Through PowerShell
You can also try PowerShell to query the same firmware information.
Go to Start > Windows PowerShell > Run as administrator. Depending on your Windows installation, you may see Terminal or Windows Terminal instead. Open it with administrator privileges.
Enter:
(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey
Press Enter and check the result.
If a firmware-embedded key is available, PowerShell may display it. If nothing appears, this does not necessarily indicate an activation problem. Your PC may simply be using a digital license or another activation method.
4: Check Your Windows Purchase Email
If you purchased Windows digitally, don’t forget about your original purchase confirmation.
Go to the email account you used when buying Windows and search for terms such as Windows product key, Windows purchase, Microsoft order, or the name of the retailer.
Microsoft explains that a digital copy purchased from an authorized retailer may provide the product key through the confirmation email or a digital locker operated by the retailer.
If you purchased directly from Microsoft, check the confirmation email and your order history associated with the account used for the purchase.
5: Check Your Windows Packaging or Certificate of Authenticity
If you purchased a physical copy of Windows, the product key may be much easier to locate.
Go to your Windows product box > product key label or card. Depending on the type of Windows package you purchased, the key may be printed on a label or included inside the packaging.
For PCs that originally came with Windows, check the Certificate of Authenticity (COA) or documentation supplied with the computer. Microsoft identifies the device packaging and COA as possible locations for a product key.
For a refurbished PC, check the paperwork supplied by the refurbisher. Microsoft notes that the refurbisher is responsible for providing the Windows product key for a refurbished device when applicable.
6: Check Your Retailer’s Digital Locker
If you bought Windows from an authorized online retailer, the retailer may have stored your purchase information in an online account.
Go to the retailer’s website > Sign in > Account > Orders or Digital Products > Windows purchase.
Look for an entry containing your Windows license or product key. The exact menu names will vary between retailers.
This method is worth checking if you no longer have the original email but still have access to the account you used to make the purchase.
7: Check Your Microsoft Account and Digital License
If you upgraded to Windows 11 from an activated version of Windows, you may have a digital license instead of a separate Windows 11 product key.
Go to Settings > System > Activation and review the activation message.
If Windows reports that it is activated with a digital license linked to your Microsoft account, you generally don’t need to recover a 25-character key just to reinstall Windows on the same hardware. Microsoft recommends linking your digital license to your Microsoft account, particularly if you might make a significant hardware change later.
This is one reason you shouldn’t assume that a missing product key means your Windows license is missing.
8: Check Your PC Manufacturer’s Documentation
If Windows 11 came with your desktop or laptop, check the manufacturer’s original documentation.
Go to PC documentation > Windows license information > Product key or COA.
Some manufacturers provide the licensing information on a label, card, documentation, or through firmware rather than displaying the key inside Windows.
If the computer uses an embedded OEM key, Windows Setup can detect and use the firmware key automatically during installation. Microsoft notes that the Windows Setup product-key screen may not appear when a product key is found in the device’s firmware.
Don’t Confuse the Current License With an OEM Key
This is an important point if you run more than one product-key retrieval method.
The key returned from your computer’s firmware can be the original OEM key, not necessarily the key that was used for a later Windows activation or upgrade.
For example, suppose your laptop originally shipped with Windows 11 Home and you later upgraded it to Windows 11 Pro. The firmware may still contain the original Home key.
So, don’t assume that every key you discover represents the edition currently activated on your PC.
This also explains why different tools can sometimes report different licensing information.
Use the Product Key Only When You Actually Need It
Once you’ve found a key, keep it somewhere secure. A Windows product key is a licensing credential, so avoid posting it publicly, sharing it in screenshots, or sending it to strangers online.
If you’re reinstalling Windows 11, you may not need to manually enter the key. On supported systems, Windows Setup can automatically detect a firmware-embedded key. If your PC uses a digital license, Windows can also reactivate after installation when the correct edition is installed and the device connects to the internet.
To change an existing product key, go to Start > Settings > System > Activation > Change product key and follow the prompts.
FAQs
Can I find my Windows 11 product key in Settings?
Usually, Settings > System > Activation shows your activation status rather than displaying the complete 25-character product key. If Windows uses a digital license, there may be no traditional key for Windows to display.
Why does Command Prompt show nothing?
A blank result generally means Windows couldn’t retrieve an OEM key from the firmware. Your computer could instead be activated with a digital license, or the key may not be stored in UEFI firmware.
Is the Windows 11 product key stored in BIOS?
On many OEM computers, the product key is stored in UEFI firmware rather than traditional BIOS terminology. Microsoft refers to this OEM mechanism as OA 3.0.
Do I need my product key to reinstall Windows 11?
Not necessarily. If your PC has a digital license or an embedded firmware key, Windows Setup can often handle activation automatically. Microsoft specifically notes that Setup may automatically apply a firmware-stored product key.
Can I use an OEM Windows key on another computer?
An OEM key embedded in a manufacturer’s computer is associated with that device. It should not be treated like a transferable retail license.
What if I upgraded from Windows 10 to Windows 11?
You may have a digital license rather than a separate Windows 11 product key. Check Settings > System > Activation first to see how Windows is activated.
Should I use third-party product-key finder programs?
You generally don’t need third-party software for this task. Start with Windows Activation settings, Command Prompt, PowerShell, your purchase records, and your original Windows documentation. These methods are safer and easier to verify.
Summary
Finding your Windows 11 product key isn’t always about locating a single code inside Windows. First, check Settings > System > Activation to determine whether your PC uses a product key or a digital license.
If Windows came preinstalled, try the Command Prompt OEM key method because the original key may be embedded in your computer’s UEFI firmware. You can also try PowerShell, check your purchase confirmation email, look through your Windows packaging or COA, and review your retailer’s digital account.
Most importantly, don’t worry if you can’t find a 25-character key. A digital license can activate Windows without requiring you to enter or retrieve a traditional product key. If your goal is simply to reinstall Windows 11 on the same computer, you may already have everything you need for automatic activation.
