My Acer Aspire desktop computer was specifically made with Windows 7 installed. I did the free upgrade to Windows 10. My hard drive then stopped spinning, so I have to get a new one. I have recovery discs for both Windows 10 and Windows 7. Am I correct to believe that neither of those will now work with a new hard drive and that I must get a new version of Windows? If so, does anyone know how much longer Windows 7 will be updating security features like Microsoft Security Essentials and Windows Update? I heard a rumour that both were going to be stopped soon for Windows 7. If I have to buy a new OS I would prefer Windows 7 but if it won't be worth my money I will get Windows 10.
