Regarding going to Windows 10 , this one is 10 but as said the laptop is 7. Some time ago I took it to our local pc man who when I asked about doing that he replied I am wasting my money.
Well, he is welcome to his opinion and we don't know how much he would charge you, so we can't form an opinion on the value. We also don't know when this was, pre MS announcing they were pulling support finally for Win 7, or post that announcement?
Now running Win 7 on the internet, with MS support for that OS finally pulled would be wide open for hacking. If using a Win 7 machine accessing the internet, can you afford not to be protected?
The change from Win 7 to the very latest Win 10, is actually free, any costs would have been his charges.
MS only officially offered a free upgrade for a period, now well expired.
BUT, the reality is that using the link I gave, a free update was still working, when not too long ago I used it. I suspect it still will be for those who try.
What was, probably is, on offer, is any computer running a legitimately licensed OS, from Win 7 upwards, can be legitimately and for free, be upgraded to the latest version of Win 10.
I suspect it is for people who screw up their copy or replace their HHD, they can get their OS back.
As I said, I have quite recently upgraded a Win 7 machine to Win 10.
All the licence info MS wants to accept you have a right to Win 10, is imbedded in your motherboard. If they ask you for it and you can't give it, then it simply goes and finds it for itself.
Now the question is, do you want Win 10, and can a Win 7 machine run it.
The machine most likely can run Win 10, in some ways it runs easier. If you want to go on the internet you really should "want" Win 10 for security reasons.
Don't linger too long, Win 10 is also on its way out, May ????
Given its upgrade options after then, who knows what offers will be about, though it seems Win 10 to the next version will be. But Win 7 right to the new OS, we can only speculate about???
Sorry for any typos spelling etc.
