Q: My laptop running 10 crash and need to re-install it. When re-install it, it popup for the product key which I don’t have. What should I do?
Chicagotech.net: Since you previously had Windows 10 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option ‘I am Reinstalling Windows 10 on this PC’, and activation will not be an issue, your PC willhave a digital entitlement stored on the Microsoft Activation Servers Make sure you install the same Edition of Windows 10 (Home, Pro . . . etc.) you previously had installed to avoid Activation issues
