I spent 2 days just going through all the settings after the change from 8.1 to 10 on my Surface Pro 3. I haven’t migrated my Windows 7 desktop yet.
Performance is slower, which is typical of an OS upgrade compared to a clean install. Since the Surface Pro 3 is both table and PC, I’m still toying with whether or not I prefer tablet mode or standard mode. Standard mode is too small for touch screen, but it is more convenient. Standard mode will be my default when docked with a full size mouse and keyboard. But I typically run tablet mode when mobile.
I don’t have any comment on the IE replacement yet. But MS still needs more apps in its store.
Solid Edge and Fusion 360 still run fine, and that without SE officially being supported on that OS.
