My sons all have upgraded with no issues, so I said what the heck and let it finish the set up.
Other than not liking Edge very much (I went back to IE for the time being) it is running without an issue and everything is fairly intuitive.
Some silliness - such as calling programs APPS, etc. -- but all in all I am not displeased.
I purchased a new laptop back in December as a Christmas present to myself (an HP Pavilion Notebook -17 inch HD screen and I love it!) that came with Windows 10.
I had Windows 7 on my old laptop, a Toshiba Satellite that was getting very cranky, but I’ve had no issues adjusting to Windows 10. I found it rather easy to get used to. Sure there was a few things that briefly stumped me at first like finding programs on the app menu, but nothing major. I actually like the clean interface.
IE will be in your ‘APPS’ menu. I found it quite easily and pinned it to the taskbar. Also, there is a menu option in Edge to import Favorites if you decide you like Edge.
I use Chrome as my default browser and use IE as my secondary. Like you, I am not too fond of Edge, I actually like and prefer Chrome. I used a USB thumb drive to down load all my files from my old laptop to my new one and also performed an export of all my browser favorites, then importing them to both Chrome and IE and Edge on the new one and everything, and all my bookmarks, favorites came back up perfectly. I also found it easy to pin my most often used programs to the Task Bar.
At the same time that I bought the new laptop, I purchased Office 2016 and I have to say that I really like that as well.
