I recently installed W10 pro on my PC . Very smooth transition , i also applied Semlers W10 set up guide regarding privacy options.
Then i installed "Open Shell" for that W7 look, with good results , very smooth and stable. Unfortunately my laptop cant handle W10 so i went for Linux Mint .
I didn`t want to upgrade , i loved 7 but happy i made the move, very pleased. So i say go for it, but take time to go through all settings . Semlers guide is really good. Hope this helps you decide.
