I updated my laptop which had been running Windows 8 and it all looks pretty much the same, so if you're used to Windows 8, I'd say go for it.
However, on my main PC computer I am hanging on to Windows 7 until they pry it from my cold, dead hands..... Windows 8 and 10 wants very extensive internet access, which I do not always have, and seems really designed for touch screen access which my laptop has but my PC does not.
The change from Windows XP or 7 to Windows 8 or 10 is the hardest part - the screens are very differently set out. I'm not recommending my 85 year old father ever shifts over.....
