This morning I installed Win 10 and all went perfectly.
It took about an hour to install.
It is installed on what was my Win 7 computer with Intel Core i5 CPU 760 @ 2.80GHZ, 4,0GB RAM, AMD Radeon HD 6800 Series.
I checked the games Dreamfall Chapters, Lumino City and Tengami that I have on my computer from Steam and they all started well and played OK for a few minutes.
I am know going around it to see what it looks like.
