I'm not having problems running Windows 10 on a PC.
It runs from the desktop and isn't that different than Windows 7 in overall feel and appearance.
Once they get all the bugs worked out I think it will be pretty easy to use.
Many things are easier to access then they were in earlier versions of Windows.
There is going to be some learning curve, many of the menus are different but the fact that you can type almost anything you want to get to into the search box and get to it directly makes it fairly easy to get to anything you want to.
It's the first OS that I've run without a third party interface since Windows XP.
im not having any issues with the OS itself, its just that everything is obvioustly designed to be touchscreen friendly.. and it looks, and feels awefull..
i've had Win10 for 3 weeks now, and i hate it.
and the simplified style that they're going for looks more like its been made by a child.
