The upgrade for me did not goes as well as it could. The Task bar did not look right and the Edge browser did not seem to be installed anywhere that I could find. I installed as an upgrade again and the Edge browser appeared, but the Task bar still did not look right.

I search, but could not fin much about the task bar issue. I installed a 3rd time, but this time without upgrading the programs, basically a clean install. This time all looked correct, but without any programs from Windows 8.

I did have a small issue with a Tapi driver with one VPN software, which I was able to fix.

The Start page and Windows "Apps" look a lot better then Windows 8.1, which I never liked. I'm sure as time goes by there will be many more issues that come up
