Finding Your Windows 10 Product Key: A Step-by-Step Guide
Step 1: Check Your Windows 10 Installation Media
To find your Windows 10 product key, you first need to check your installation media. This is usually a USB drive or a DVD that contains your Windows 10 installation files. If you have a USB drive, insert it into your computer and restart it. If you have a DVD, insert it into your computer’s DVD drive. The installation media should be recognized by your computer, and you should see the Windows 10 logo.
Step 2: Check Your Product Key on the Installation Media
Once you have checked your installation media, you should see a screen that displays your product key. This is usually located at the bottom of the screen, below the "Product Key" field. Note: If you don’t see your product key on the screen, you may need to restart your computer and try again.
Step 3: Check Your Product Key on the Windows 10 Settings App
Alternatively, you can check your product key on the Windows 10 Settings app. To do this, follow these steps:
- Go to Settings > Account > Sign-in options.
- Click on Change your product key.
- Enter your product key and click Save.
Step 4: Check Your Product Key on Your Windows 10 Installation Files
If you have installed Windows 10 from a USB drive or a DVD, you can also check your product key on the installation files themselves. To do this, follow these steps:
- Go to the installation files that you installed.
- Look for a file called setup.exe or setup.exe.nls (depending on the language).
- Open the file and look for a line that starts with Product Key.
- Take note of the product key that appears on this line.
Important: If you have installed Windows 10 from a USB drive or a DVD, you may need to use the product key that is printed on the USB drive or DVD. This is because the product key on the installation files may not be the same as the one that you entered during the installation process.
