Will my daughters lap top have to upgrade to Window's 10?

Keep reading more and more articles on the forcing by Microsoft.
Until now I' ve got none of these "upgrade now" notices… But maybe because it an old Lenovo T 410 and is not compatible with 10. For the moment its running 7 pro.
I know from past experience with "serious" upgrades on Mac that usually everything crashes and you end up having to buy a new computer… Feed back please

No two finger scroll after updating to Windows 10?

I have a lenovo yoga 2 pro. After updating to Windows 10, I can no longer two finger scroll. I'm not sure what the problem is, considering that two finger scroll is turned on (Settings > Devices > Mouse and Touchpad > Additional Mouse Options > Device Settings > Settings > Multi Finger > Two finger > and then check both Enable vertical scrolling and Enable horizontal scrolling)
Any clue how to fix it or where I should ask where people would know?

What's wrong with my windows 10 Lenovo?

Well, I'm sure a virus or two or several dozen have been released into it. I first noticed an issue when I was trying to download steam but it wouldn t download. The Internet was being flakey, and then it just wouldn t recognize any networks. I decided to try resetting the whole thing to factory settings because it's fairly new, just a few spreadsheets and apps on it.
So when I tried to do a system restore, it said there was a problem resetting your PC. I've tried hard booting it but it either goes to the login screen or turns back off when I start up.
Is geek squad my last hope?
