Desk top computer froze and whatever we did we couldn’t get past blue screen it was stuck on asking for keyboard to be set up. So, realising I would lose everything I decided to factory reset it but didn’t realise I would lose Windows 10 which was upgraded when it was free to do so. The computer is getting on a bit but after latest upgrade which we think was the issue I am now left in the dark ages. Please can anyone suggest which is best operating system to use now? I do not want to pay the charges for upgrading as I do have Windows 10 on a laptop.
