On the not so good side. It is hard to make search only search my machine and not the internet. You really feel this with a slow connection. Sometimes the start menu will not come up when I hit the windows logo. They kind of dumbed down the windows update making so you can't pick which ones you want now. That may be a good thing for most folks but I don't like it. Settings in general are an ugly mix of modern and classic. Device Manager and some of the Network settings are classic but the tray interfaces are all moder. The Moder App version One Note is confusing. It is even more confusing that you end up with two versions of OneNote if you install office. You can set the zoom / scale differently on multiple monitors but you sometimes get weird font behavior if you drag a window across the monitors.
It feels like an improvement over ghastly windows 8 , which I previously ran on all machines so I could get task bars on all monitors.
