I am in the midst of switching over to Windows 10, after many happy years on 7. I was very reluctant to switch because of all the things I read about how Windows had tried to put a desktop gui together with a tablet and phone one. But it turns out that Windows 10 is pretty much like 7.<p>There is one huge difference, that's accounts. In 7 you get in with a password, but in 10 you can also use a pin. Also 7 has two types of account, administrator and standard. In 10 there are two more variables, Microsoft account vs local, and family vs other user, with a different procedure for creating each.<p>Also there is cortana, but I haven't use it except for the initial setting up.<p>Let me add that I have found David Pogue's Windows 10 The Missing Manual very helpful.
I find it odd that on the blue screen notification they stated that they "Strongly Recommend" you to upgrade to Windows 10 on a "New PC".
