It's not that much faster than 7, (if at all).
Ya lose several valuable Free apps, which you will be allowed to buy, and you will be spied upon and solicited without end.
I am fine using windows 7. This is for a friends laptop.... to upgrade it out of some problems.
^^^^^ This! ^^^^^
I've had to help family and friends revert back to Windows 7 when they did not like Windows 10 at all. At least they have 30 days to switch back if they do not like it. Personally, I'd stick with Windows 7 till support runs out, as it is one of the best operating systems Microsoft has come up with, IMO.
Disclaimer: I prefer Linux operating systems (Ubuntu, Zorin, Mint) but when I use Microsoft Windows operating systems, I prefer Windows 7. Microsoft got that one right and really no reason to upgrade unless you have to, IMO.
