Windows 10 is suggested although Windows 7 is what I preferred, why? very easy because I suppose internet is a must for everyone or every computer nowadays, if that's true then Windows 10 is the only choice, my netbook use Windows 7 and it poped me up 2 times to remind me to backup my data, why? the pop up is system or Microsoft official, it says Windows 7 will no longer be supported in the early of next year can tell me to backup my data, well my version of speaking is that, they give up on Windows 7 and if I keep using it afterward then my data will be at high risk of safety, there is no choice at all just like you cannot choose to use or not use internet
