How to Find Your Windows Product Key: 5 Easy Methods
The absolute fastest way to find your Windows product key is to open Command Prompt as an administrator and type: wmic path softwarelicensingservice get OA3xOriginalProductKey. Your 25-character product key will instantly appear on the screen. However, depending on how you purchased Windows, your key might be stored digitally, on a physical sticker, or in an email receipt.
Whether you are reinstalling Windows, transferring your license to a new PC, or just want to back it up, losing your 25-character license key can be incredibly frustrating. Fortunately, Windows usually hides it right inside your computer’s system files.
Here are the 5 easiest methods to find your Windows 11 or Windows 10 product key in under two minutes.
1. Use the Command Prompt (Fastest Method)
If your computer came pre-installed with Windows (an OEM license), the product key is embedded directly into your computer’s motherboard. You can easily pull it using the Command Prompt.
- Click the Start button and type cmd.
- Right-click “Command Prompt” and select Run as administrator.
- Copy and paste the following exact command and press Enter:
If successful, your 25-character key will appear on the next line. Note: If the space is blank, it means you have a Retail or Digital license instead of an OEM motherboard license. Try the next method!
2. Use PowerShell to Find Your Key
Similar to Command Prompt, Windows PowerShell is a powerful tool that can dig into your system’s BIOS to extract the embedded product key.
- Right-click the Start button and select Windows Terminal (Admin) or Windows PowerShell (Admin).
- Paste the following command exactly as written and press Enter:
Your license key will be displayed immediately.
If you discovered your current license is a volume key, pirated, or simply won’t activate, it might be time for a clean slate. SortedKeys provides genuine, lifetime licenses delivered instantly to your email.

If the command line methods didn’t work, your key might be stored in the Windows Registry. This method requires a bit of digging, but it is highly effective for Retail licenses.
- Press Windows Key + R to open the Run dialog.
- Type regedit and press Enter.
- Navigate to this exact folder path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform - Look for the file named BackupProductKeyDefault. The data listed next to it is your 25-character product key!
4. Check Your Microsoft Account (Digital Licenses)
If you upgraded from Windows 10 to Windows 11 for free, or if you bought Windows directly from the Microsoft Store, you likely have a Digital License instead of a traditional 25-character key.
Digital licenses are tied to your Microsoft Account email address. To verify if you have one:
- Go to Settings > System > Activation.
- Look at the “Activation state”. If it says “Windows is activated with a digital license linked to your Microsoft account,” you don’t actually need a 25-character key! Just log into your new PC with the same Microsoft email, and Windows will activate automatically.
5. Check Physical Stickers and Email Receipts
If you bought your PC at a retail store, or if you bought a software key online, your key exists in the real world:
- Laptops & Pre-builts: Look at the bottom of your laptop, under the battery, or on the back of your desktop tower for a holographic Certificate of Authenticity (COA) sticker.
- Email Receipts: If you bought your key from an authorized retailer like SortedKeys or Amazon, search your email inbox for terms like “Windows License”, “Product Key”, or “Activation Code”.
Frequently Asked Questions
Why is my Command Prompt product key blank?
If the wmic command returns a blank space, it means your computer does not have an OEM license embedded in the motherboard. You likely have a Digital License tied to your email, or a Retail license purchased separately.
Can I use the same product key on a new computer?
It depends on the type of key. Retail keys can be transferred to a new computer (as long as you deactivate the old one). OEM keys are permanently locked to the motherboard of the first computer they were installed on and cannot be transferred.
What happens if I lose my product key?
If you have a Digital License, nothing happens—just log in with your Microsoft account. If you lose a traditional Retail key and cannot recover it via the Registry or your email, you will unfortunately need to purchase a new license key to activate Windows.
