I have a Lenovo laptop preinstalled with widows 8.1 I want to down grade to windows 7 when I installed he ask me for a key or I have 30 days so can you provide me with the key. Lenovo z50 70
The product key is in the bios and since the unit came with win 8.1 it is for that product only. You should have the product key when you downgrade to win 7.
