This wikiHow teaches you how to find your 25-character Windows 8 product key in a variety of ways. If you can boot into Windows, you can find the key using the command prompt, Windows PowerShell, or a free app called ProduKey. If the PC won't boot, you may find the key on a sticker somewhere on the hardware, the DVD packaging (if you purchased Windows separately), or in your email (if you purchased Windows online through Microsoft). If you're unable to retrieve the key with any of these methods, you can purchase a replacement key for only $10 through Microsoft.

Things You Should Know

If you can't get into Windows, look for a sticker on your PC with a string of 25 characters or check your email to see if you saved your Windows purchase confirmation.
Open the Windows command prompt and click Run as administrator. Type wmic path softwarelicensingservice get OA3xOriginalProductKey and hit ↵ Enter. Your number will appear.
Try other apps and programs such as ProduKey and Windows PowerShell.

Finding the Product Key if You Can't Get Into Windows

1
Look for a sticker on your PC. Starting with Windows 8, Microsoft no longer requires that Certificate of Authenticity stickers be placed on PCs that come pre-installed with Windows 8.^{[1]

If you have a desktop PC, look for a sticker somewhere on the tower (not the monitor/screen). If you're using a laptop, check the bottom of the unit or underneath the battery cover.
- If you are able to log in to Windows 8, you can use any of the other methods to quickly pull up your product key.
- The product key is 5 sets of 5 characters separated by hyphens (e.g, XXXXX-XXXXX-XXXXX-XXXXX-XXXXX).
2
Check your Windows 8 DVD packaging. If you bought a physical copy of Windows 8 on DVD, the product key should be included in the DVD packaging or on the case. It could also be printed on a sheet of paper or card that came inside the package.

Check your email if you purchased Windows 8 online. Did you buy Windows 8 from Microsoft's website? If so, you'll find your 25-digit product code in the email confirmation message from Microsoft.^{[2]

Connect the Windows hard drive to another PC. If you're unable to boot the computer up but the hard drive with Windows 8 installed still works, you can use a free tool called ProduKey to retrieve the key from the hard drive. To do this:
- Remove the Windows hard drive from the non-working PC. See How to Remove a Hard Drive to learn how.
- Connect the drive to another PC as a secondary (slave). One easy way to do this is to put the drive into an external hard drive enclosure and connect it to the other PC.
- Follow the steps to download and run ProduKey in this method: Using ProduKey.
- Once you run ProduKey, press the F9 key to open the Select Source menu.
- Select the radio button next to "Load the product keys of external Windows installations from all disks currently plugged to your computer."
- Click OK to display the product key. The key from the Windows 8 hard drive will appear next to "Windows 8."

Contact Microsoft to request a new product key. If you are still having trouble finding your product key, you can purchase a replacement key for $10 from a Microsoft support agent. Here's how:
- Call 1 (800) 936-5700. This is a paid Microsoft support line ($40-60 per issue), but you will not be charged for support if you are just calling to purchase a replacement product key.
- Follow the phone prompts to reach an agent who handles product key issues.
- Tell the representative that you can't access your Windows 8 product key. Provide the representative with any requested information, which may include your computer's serial number (if Windows 8 came with your PC), information from Windows 8 DVD (if you have the media), and your credit card details once your request is processed.
- Write down the product key exactly as it is read to you by the agent. Read it back to confirm you have written it down correctly.
- Follow additional any additional activation instructions provided to you by the agent. You may be transferred to another department to activate the key before it can be used.
