How to Find the Product Key of Your Windows 10 Computer Even If Its Dead

A product key is a unique 25 digit code that is used to activate Windows. It is also like giving your PC an identity which is different from other PC’s. Activation also helps verify that Windows hasn’t been used on more PCs than the Microsoft Software License Terms allow. It may so happen that you need those keys once again, reinstalling Windows or when switching to a second PC, and this is where things get tricky. Lets find out how to find a product key of Windows.

Your product key is on a card inside the box that the Windows DVD came in, or in an email that shows that you bought Windows. There are other two scenarios which are mentioned below:

  • Printed on a sticker: Some older PCs (mostly the one with Windows 7) has a sticker at the back with the product key written on in. Like my old Lenovo laptop which came with Windows 7 has a sticker at the back with the product key mentioned on it, whereas the new ASUS doesn’t have one.
  • Embedded in your PC’s UEFI firmware: Many newer PCs that come with Windows 10 or 8 for instance, use a new method. The key for the version of Windows the PC comes with is stored in the computer’s UEFI firmware or BIOS. If you’re installing the same edition of Windows the PC came with, it should automatically activate and work without you needing to enter a key. You don’t even have to know the key. However, there are numerous other tools which will help you find your product key in a single click.

Knowing your Product Key is helpful when you re-install your Windows or any other Microsoft product. To know your product key you can try out the tools mentioned in the post below.

NirSoft’s ProduKey

It can be used to find the product key even when you’re not able to boot your PC. All you have to do is download ProduKey, unzip it, and then run it. It automatically shows all your product keys in a fraction of seconds.

If you want to recover a key from a dead computer, you can connect your hard drive to another PC and then run ProduKey. After that, File> Select Source to point to the external Windows directory.

This is another great software to find your product keys. Download Key Finder from here and follow the installation process to install it on your computer. Once you start the program, it will scan your system and find the product keys of supported programs, including various versions of Windows and Microsoft Office.

When the scan is complete, the tool will display a window with entries in the left pane for whatever installed versions of Windows and Office it detected. Click the entry for your version of Microsoft Windows to reveal the key and other information about the installation. The key will be listed under ‘CD Key’ on the right side of the window. That’s it!
