right now OEM earn money from computer possible 800Dollars + Win 10 ? its too early for some1 buy win 10 except the techinals and supporters..
I think people are misunderstanding the term "RTM", which traditionally was when MS released the bits to OEMs/Partners which it looks like they did. So technically Windows 10 has hit RTM, we are just waiting for General Availability. RTM literally means Release to Manufacturing, this is so it can start to be preloaded on devices. Windows 10 however is never technically done, Microsoft is aiming to have Windows as a service which is why it looks like MS is avoiding the term.
So if someone buys Windows 10 after 29 July, he will get 10+ upgrade in windows update, it makes no sense?
That is exactly how it went for Win 8 and Vista release and even prior to that. Nothing new on that...
