How to find Windows 7 product key

Using Belarc Advisor

As we mentioned above, Windows has stored you product key. However, it is in an encrypted form, so that even if you find it, you won’t be able to use it. In the case of Windows 7, you will need the help of a third-party software to find out what your product key is.If you are using Windows 8, 8.1 or 10 you have other options – check out the next steps.

In our guide, we’ve used a program called Belarc Advisor – it is a free tool that you can download online. Here are the instructions on how to use Belarc Advisor so as to regain your product key:

1. Download and install the program. After the installation, it will automatically scan your computer. You may be displayed a dialog window asking you whether you want to check for new security definitions, should this happen, click on NO.
2. Once the scanning is over (won’t take more than a few minutes), a browser tab will open, containing a detailed report for your PC. Scroll down until you reach a section labeled Software Licenses.
           
3. You will find your Windows 7 product key if you look in Microsoft – Windows 7 (your Windows 7 version). It should be a 25-character key containing both letters and numbers.
4. Copy the key and make sure that you either save it on another device or simply write it down and make sure that you don’t lose the piece of paper.

How to find Windows 10 product key

If you’re a Windows 8.1/10 user, you may not need to download a third-party software and instead use either the command prompt or the power shell tools that come with Windows itself. This may require a bit of extra work, but you won’t need to install any applications in order to find your Windows 10 product key.

Using Command prompt.

1. To open the command prompt, right-click on the Start Menu and select Command Prompt (Admin).
     
2. Copy the following command, Paste it in the Command Prompt window and hit Enter: wmic path softwarelicensingservice get OA3xOriginalProductKey 
3. After a few moments the product key should be displayed below the command you’ve just entered.

If the Command Prompt is giving you trouble try Power Shell.

Using Power Shell

1. Open your Start Menu and in the search field type powershell
2. From the search results Right-click on the one named Windows PowerShell and select Run as Administrator.
3. Copy the following command in the PowerShell window and press Enter: powershell “(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey” 
4. Your product key will be displayed shortly after – make sure that you save it so that you’d be able to use it later, when needed.
