I agree with the two points made. I had the expensive Windows 7 Ultimate which had special features for a home theater. It also had the games I liked and all worked well. I did not knowingly authorize Microsoft to delete the OS and install Win 10. Each time a popup asked if I wanted Win 10 I said no. Microsoft did it anyway.
I now have a problem with my AMD display driver failing often and an OS that stinks. If I revert back to Win 7, I fear that Microsoft will either quit supporting it or will again overwrite it as before. Win 10 took a full day to fix bugs and they are not all gone yet.
The solution to go to a third party website to download Chess Titans is too scary for me. I want a Microsoft web offered solution. A friend told me to be careful of Softonic. Viruses have hit me many times through the many years I have been in computing, thus I am not willing to take chances.
