I update from windows 7 64bit to windows 10 for registration of w10. Then i made a clean install of windows 10 and install the panasonic cf 53 mk2 w8.1 driver bundle afterwards. Then i leave the toughbook updating automatically old drivers (realtek audio, intel video and whatever he did more don't know jet).
It is awesome. Windows 10 works fine, up now i don't have any issues. I use windows 10 now for about a year and i am satisfied.
