The Win 10 upgrade I did had no real problems and continues to work well. As far as Edge vs. IE, the user also did not like Edge, so I unpinned Edge from the taskbar, pinned IE in its place and all is well. If you are looking for IE, go to the start menu, click on all apps, scroll down to "Windows Accessories", find "Internet Explorer", right click and click on "Pin to Taskbar". Easy-peasy...
