Hello there,
If you have upgraded your computer from Windows 7 to Windows 10 and want to activate Windows 10 using your Windows 7 product key, follow these steps:
Find Your Windows 7 Product Key: Before you proceed, ensure that you have your Windows 7 product key available. It is usually found on a sticker on your computer or the retail packaging of your Windows 7 installation disc.
Upgrade to Windows 10: If you haven't already upgraded your computer to Windows 10, you need to do that first. You can do this by using the Windows 10 Media Creation Tool, which allows you to download and install Windows 10 on your computer. During the upgrade process, you'll be asked to enter your Windows 7 product key. Follow the on-screen instructions to complete the upgrade.
Check Activation Status: Once you have upgraded to Windows 10, go to Settings > Update & Security > Activation to check the activation status. If Windows 10 is not activated, proceed to the next step.
