But I never paid for any windows till date, yet my desktop says Windows activated, license linked with my MS account. While I did upgrade 3-4 laptops(came with legal windows) when the schemes was running, I updated my desktop(ahem version) from Win 7 to 10 in 2018 by downloading the ISO from MS site, way later after the scheme was over. I was also saving some money to buy a license but then thought, the license is linked to my mail id, it is already activated so why bother with a new license..
