Need Windows 8.1 product key after clean install Windows 10
I have a Lenovo S21E-20. I purchased machine new, it came with 8.1 loaded and as soon as it was turned on it said "free upgrade to Windows 10 available". Due to small SSD memory, could not simply upgrade from installed to Windows 10. I used a clean install using a USB. After installing Windows 10, there was no room left on SSD. So in order to continue, I deleted Windows (old) folder. Now the computer is asking me to go to settings and activate but it will not do so, it is asking for a product key that I do not have.
Is there a way to achieve this activation?
