How to Find Your Windows 10 Pro Product Key: 7 Reliable Methods

30.04.2025

Need to find your Windows 10 Pro product key before reinstalling Windows, replacing a hard drive, or moving your license? First, check Settings > Update & Security > Activation. If Windows says it is activated with a digital license, you may not need to enter a product key when reinstalling the same Windows edition on the same computer.

To retrieve a stored 25-character Windows 10 Pro product key, you can use PowerShell, Command Prompt, the Windows Registry, your original purchase records, or Magic Recovery Key. Magic Recovery Key is particularly useful when manual commands return a blank result or when you need to recover license information from an old or non-bootable Windows drive.

Quick Answer:

The best method depends on your license type. Use PowerShell or CMD to check for an OEM key embedded in the PC firmware. Check your purchase email or packaging for a retail key. If Windows uses a digital license, a visible product key may not exist. For an old or inaccessible drive, scan it with Magic Recovery Key before formatting or reinstalling Windows.

2026 Update:

Microsoft ended standard support for Windows 10 on October 14, 2025. Windows 10 computers still work, but they no longer receive regular security fixes unless they qualify for an extended update program. Recovering your license information remains useful when reinstalling Windows, upgrading hardware, or moving to a supported Windows version.

Why You Need Your Windows 10 Pro Product Key

Before trying to recover a key, check whether your computer uses a product key or a digital license.

A Windows 10 Pro product key is a 25-character code in the following format:

XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

A digital license activates Windows through Microsoft’s activation servers without requiring you to enter or view a traditional key. To check your activation type, open Start > Settings > Update & Security > Activation.

You may see one of these messages:

  • Windows is activated with a digital license.
  • Windows is activated with a digital license linked to your Microsoft account.
  • Windows is activated using your organization’s activation service.
  • Windows is not activated.

If your Windows 10 Pro installation is activated with a digital license, reinstalling the same edition on the same hardware will normally reactivate after the computer connects to the internet. A recoverable product key is more important when you purchased a retail license, plan to replace major hardware, or need to keep a license record before migration.

Why Is My Windows 10 Pro Product Key Not Showing?

A command may return a blank result for several legitimate reasons:

  • Windows is activated with a digital license.
  • The computer does not have an OEM key embedded in its firmware.
  • The license is managed through KMS or volume activation.
  • The installed edition does not match the original firmware key.
  • The Registry contains only a generic installation key.
  • The original activation information was removed or replaced.
  • The key is stored in purchase records rather than on the computer.

Check the Activation page before assuming that the key has been lost.

Method 1: Instantly Recover Your Product Key with Magic Recovery Key

The fastest and most reliable way to find your Windows 10 Pro product key is by using Magic Recovery Key — an automatic product key finder designed to recover lost or hidden license information from your system or external drives.

How it works:

1. Download and install Magic Recovery Key from Amagicsoft.com.

Download Magic Recovery Key

Supports Windows 7/8/10/11 and Windows Server

2. Click “Registry Keys” tab under “Local”.

3. On the right panel, view the Applications Registry Keys. Magic Recovery Key will display all keys for installed software. Select and copy the targeted serial numbers. Additionally, you have the option to click either “Copy” or “Save” for your convenience.

This method is suitable for users who want to back up Windows, Office, Adobe, SQL Server, and other supported software keys without manually searching multiple system locations.

Method 2: Find the Windows 10 Pro Product Key with PowerShell

PowerShell is the preferred built-in method for checking whether your computer has an OEM product key embedded in its BIOS or UEFI firmware.

  1. Right-click the Start button.
  2. Select Windows PowerShell (Admin) or Terminal (Admin).
  3. Enter the following command: (Get-CimInstance -Query ‘Select * from SoftwareLicensingService’).OA3xOriginalProductKey
  1. Press Enter.

If a firmware-embedded key exists, PowerShell will display the 25-character key. If the result is blank, your computer may use a digital license, retail license, volume license, or another activation method. A blank result does not necessarily mean that Windows is unlicensed.

Method 3: Find the Windows 10 Pro Product Key Using CMD

Command Prompt can also retrieve an OEM key embedded in the device firmware.

  1. Type cmd in the Windows search box.
  2. Right-click Command Prompt and select Run as administrator.
  3. Enter: wmic path SoftwareLicensingService get OA3xOriginalProductKey
  1. Press Enter.

This command does not reveal every type of Windows 10 Pro license. It mainly checks for the original OEM key stored in the device firmware. If no key appears, continue with the other methods below.

Note: WMIC has been deprecated by Microsoft. It remains available on many Windows 10 installations, but PowerShell should be presented as the primary command-line method.

Method 4: Check the Windows Registry

You can inspect the Windows Registry for a stored backup key:

  1. Press Windows + R.
  2. Type regedit and press Enter.
  3. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
  1. Find BackupProductKeyDefault.

Important: The value displayed here may be a backup, default, or generic installation key rather than the unique key that activated your Windows 10 Pro license. Do not assume that it can activate another computer.

Method 5: Check Your Purchase Records

The correct location depends on how Windows 10 Pro was purchased:

  • New computer: Check the PC packaging, documentation, firmware, or Certificate of Authenticity.
  • Physical retail copy: Look for the card or label inside the Windows box.
  • Digital retail copy: Search the purchase confirmation email or the retailer’s digital locker.
  • Microsoft purchase: Review the confirmation email and Microsoft account order history.
  • Organization license: Contact your IT administrator or check the organization’s volume licensing records.

Method 6: Check Your Microsoft Account and Digital License

A Microsoft account may show that a device is associated with your account, but it does not always display the full 25-character product key.

Open Settings > Update & Security > Activation. If the page says that Windows is activated with a digital license linked to your Microsoft account, keep that account linked before reinstalling Windows or making a major hardware change.

After a motherboard replacement or another significant hardware change, use the Activation Troubleshooter and select “I changed hardware on this device recently.”

Method 7: Recover a Windows Key from an Old or Non-Bootable Drive

If the original Windows installation no longer starts, avoid formatting the old drive before checking it.

Connect the old system drive to a working Windows computer using a compatible enclosure or adapter. Open Magic Recovery Key, select the connected drive, and scan the old Windows installation for stored license information.

Recovery availability depends on the license type and whether usable activation data remains on the drive. A digital license tied to Microsoft’s servers may not appear as a traditional 25-character key.

Back Up and Protect Your Product Key

Once you’ve found your Windows 10 Pro product key, make sure you back it up securely:

Save it in an encrypted password manager

Write it down and store it safely

Keep a copy using Magic Recovery Key’s “Export” function

This ensures that even after reinstalling Windows or replacing hardware, you can easily reactivate your system.

Conclusion

There is no single method that retrieves every Windows 10 Pro product key. PowerShell and CMD mainly identify firmware-embedded OEM keys, while the Registry may show only a generic or backup value. Retail keys are more likely to be found in purchase emails, packaging, or order records, and digital licenses may reactivate Windows without displaying a traditional key.

When manual methods fail—or when the original Windows installation is on an old or non-bootable drive—Magic Recovery Key provides a practical way to scan, review, and back up stored Windows and software license information before reinstalling or replacing the system.

Frequently Asked Questions (FAQ)

Where can I find my Windows 10 Pro product key?

The location depends on how you obtained Windows. An OEM key may be embedded in your computer’s BIOS or UEFI firmware. A retail key may appear in the product box, confirmation email, Certificate of Authenticity, or retailer account. Computers activated with a digital license may not have a visible 25-character product key.

How do I find my Windows 10 Pro product key using PowerShell?

Open PowerShell or Windows Terminal as an administrator and run:(Get-CimInstance -Query 'Select * from SoftwareLicensingService').OA3xOriginalProductKeyIf your computer has an OEM key embedded in its firmware, the key should appear below the command. A blank result usually means that no firmware-embedded key was found, not necessarily that Windows is unlicensed.

Why does CMD show a blank Windows 10 product key?

The CMD command mainly checks for an OEM product key stored in the BIOS or UEFI firmware. It may return a blank result when Windows uses a digital license, retail license, volume license, or organization-managed activation. You should check Settings > Update & Security > Activation to confirm how your copy of Windows is activated.

Can I find my Windows 10 Pro product key in my Microsoft account?

A Microsoft account does not always display the complete 25-character Windows key. However, it may contain your Microsoft Store order history or be linked to your Windows digital license. If the Activation page says the digital license is linked to your Microsoft account, the account can help reactivate Windows after reinstallation or certain hardware changes.

Do I need a product key to reinstall Windows 10 Pro?

You may not need to enter a product key when reinstalling the same Windows 10 Pro edition on the same computer. If the device already has a valid digital license, choose “I don’t have a product key” during installation. Windows should reactivate automatically after the computer connects to the internet.

Is BackupProductKeyDefault my real Windows activation key?

Not always. The BackupProductKeyDefault value in the Windows Registry may show a backup, default, or generic installation key instead of the unique key used to activate your computer. Before saving or transferring that value, compare it with your license records and check the Windows Activation page to determine your activation method.

Can I transfer my Windows 10 Pro product key to another computer?

Transfer rights depend on the license type and Microsoft’s applicable license terms. A separately purchased retail license may be transferable after it is removed from the previous device. A Windows license preinstalled by a computer manufacturer is generally associated with the original device. Volume and organization licenses are controlled by the relevant administrator.

Can Magic Recovery Key recover a key from a non-bootable computer?

Magic Recovery Key may retrieve stored Windows and software license information from an old system drive connected to a working computer. Recovery depends on whether the drive can still be detected and whether the relevant system and registry data remain readable. A digital license stored on Microsoft’s activation servers may not appear as a traditional 25-character key.
