Finally ... a few days I got some sort of "measles"(Windows Vista Home Premium) And the first thing differently than the old version of XP, is the graphics. Many changes, much improved ... what mai..arata well. Vista Aero .
I thought, however, that if it were a competition graphical operating systems, this would be possible only between Mac and Windows. Uhm ... it looks like I was wrong.
