well when trying to make a point you do not need to attack the person you are making the point to. I understand you may have a valid arguement, but I know of plenty of moderators here who are also technicians who disagree with you. Why do they disagree?
As to windows 10 I will agree it is different, but it is much more like 7 than 8 and it also is fine. As to the license it does show a simple number there, but the license is supposed to be binded to your Motherboard mac address. That being your motherboard mac address is supposed to be in a sense your license. I have no need to upgrade my computer again. I have a 2600k Sandybridge it is a great chip, but if I were to get a better chip I would have to change my motherboard. If i were to do that I would probably just build a new machine anyhow. That would need a new windows.
You say it is "nothing near the same as 7" exactly how? I care about performance, so far it performs the same. I came into this with skepticism myself, so unless you explain something straight and clear as to what you mean without talking down to me, I might consider what you say.
