Hello,
I am very satisfied with windows 10. I think is the most stable and secure version of windows. I work and play on windows since theyr XP version. Although I never liked the Vista version. I think it's a good thing that the producers deactivated the metro gui interface from the Windows 8 version to boot at the start, that never helped very much on a pc configuration, but it was a good thing for the tablets. I am really curious how the future will modelate the Windows platform.
Thanks!
