Thank you very much for your explanation, very helpful. That means all the old games i love so much do not work. I tried everything, lower my screen resolution ... but could not find a solution.
By the way I think that concept mentioned above is kinda stupid. What benefits do we PC users have from it? Annoying. I was stupid to delete my old Windows backup and now i have to reinstall everything. And the way Windows 10 save those backup files is stupid too, they should let us choose which drive to save/restore backups, not C drive.
