Ok I went ahead and upgraded my main Gaming PC to Windows 10 Pro.
I had a few issues, like above user I had to install Logitech Gaming Software program afterwards , as well as my Realtek onboard Audio driver, and then I got a dll License error when launching BF4. I fixed this by just downloading the corresponding dll from this package,

After a quick restart, BF4 then works.
Dont forget to turn off all your send to Microsoft crap with Customize your settings or else they will know you are a fooking Idiot!
